.......Turbo had one of his brainwaves; "why don't we dig all the way to China; then we won't need ships" he said

Any one willing to work out the hub mechanism, I haven't a clue on what's inside .

 

Things

The Skipper is very pleased to see that the Singulartrack believes that Quoka Poo is 100% successful as an aphrodisiac, as when Cappy buys a dozen oysters, usually only about 9 or 10 of them work.

 

We shouldn't pick on Captain Blimp, but in a moment of weakness during his gin fog, he told Turbo that even though he was getting a 9 or 10 response, as soon as he got close his wife told him to sleep out in the yard because his breath smells.

Meanwhile in Beijing, one of the richest men in the world, who owned 83% of all chicken and duck farms in China, Wun Tak had been reading the NES.

"Why this person using my name!?" he roared, and....

I rather think the negativity of his campaign impacted Shorten’s chances by detracting from his vote; probably more than he positively assisted the LNP.

 

Were you able to download the spreadsheet? That really told the story.

In 76% of the electorate (114 Divisions), UAP didn't get above 4000 votes; If you or I nominated and campaigned as unknowns, we could expect to get more than 4000, so strike 1 for influence.

If his negativity had worked we would have expected to see a fall away in Labor and Liberal support, an expansion of Greens and independents like Derrin Hinch, and some UAP candidates at the top end elected.

Out of the 151 Divisions, 68 (45%) were won by over 20,000 votes. In total 111 (74%) were won by over 10,000 votes.

That looks like a very solid return to two party roots to me

If you then split that by the major parties:

ALP won 46 Divisions by more than 10,000 votes (30%) of the 151 total

LNP won 58 Divisions by more than 10,000 votes (38%)

That's a  pretty impressive support for the two major parties, and the independents and Greens were almost wiped out.

From there  we have some leaks from factions within the parties as to who "won" or who "cost us" the election, but this time round I wouldn't make a guess at what happened, even if I could read the results of the Party washup meetings where they had all the data. There were quite a few Candidates sacked, including past pre-poll, where votes were wasted, and a lot of mistakes with electoral strategy, but I think most made their mind up about poor old Clive after the 50th interruption to their TV programme.

 

 

the Commonwealth’s Environment Department has to sign off projects of this magnitude.

 

It certainly does if a location is registered as a RAMSAR site, or anything else happens to trigger it as an EPBC site, but I hadn't heard of anything else.

As we know, nothing's impossible, but the EPBC Act was designed to stop the good old boys shooting all the leopard skinned parrots, or cosying up to Ministers, so I couldn't see his endless waffle influencing an EPBC Act decision.

There's a report, A Queensland river has been dammed, stopping water going downstream to the Darling River.

 

( diverted for use of cotton farming)

There are quite a few cases of illegal water harvesting. Former Federal Police Commissioner Mick Kelty has been appointed to take action agains illegal water use. 

Not everyone gets away. IBAC started a three week investigation into the City of Casey a week ago, the Age is following it with daily reports; would take your breath away.

 What would sensible people EXPECT to be the  result?  Nev

 

There can be several generations of money- makers between the original developers who buy farmland, the next generation who buy it and subdivide it, then the builders who buy lots then the new residents who are not aware they are in a swamp or on a flood plain. There are hundreds of houses going up around Koo Wee Rup, houses all built on the ground, flood level plaque in the main street with the line at my shoulders.

 So A Flood mitigation Dam does no good at all? IF you fill your tank THAT amount of water is then out of the equation and might as well have never fallen as rain as far as the normal river that drained the area is concerned.  Urban areas don't retard as much water as the original wooded area did . Stormwater drains get water way quickly to SOMEWHERE ELSE. so downstream gets a rapid rising floodwater . Farm dams fill then what is extra passes downstream. That's why they are not welcome in water catchment areas . Nev

 

To retain stormwater on the property, the basin needs to be 65% of the area of the hardstand (impervioujs house, sheds, concrete b y about 3 metres deep. No one in the urban area sets aside that much area as a retarding basin.

On the bigger scale, If you were designing an estate for 1100 houses, I would think you would calculate 100% of the estate area as receiving rainfall plus whatever the overland flow had been estimated to be from the nearby mountains. You might be as surprised as I was to find the developer calculation was 0.0355% of the estate area. With that little water spout there was no problem getting planning approval. In other words I'm talking a huge shortfall in retarding capacity rather than the mild situation you described.

........keen to be seen to be doing something to protect Australia and its workforce.

Just then Turbo received a text that the Chinese had just landed 40 D7 dozers, 15 graders, and other "stuff" on the Spratly Islands.

You wouldn't believe it but just then there was a knock on the door and Nobushi poked his head in and said: "Can I be of any help..........."

 

No, power is a fundamental concept in physics: the rate at which work is done. A rocket engine produces power (but no torque), a jet engine produces power, a man walking up stairs produces power. Your calculations are just specialized examples to calculate the power of an internal combustion engine.

 

It takes power for a vehicle to climb a hill. You can calculate the power required, and it doesn't matter whether it comes from an internal combustion engine, a rocket engine, or 4 guys pushing the car.

 

1 horsepower = the power required to raise 75kg 1 metre in 1 second.

 

or if you prefer imperial

 

1 horsepower = the power required to raise 550lb 1 foot in 1 second.

 

The thread is about props so we can dispense with expanding the thesis.

Once you understand the relationship between Torque and horsepower you can get an understanding of what prop will suit the engine characteristic.

For Example: 

You can nearly rule in or out a Wankel type rotary design on that basis alone, or

You will know why Douglas Bader crashed his Spitfire when he tried to take off in coarse pitch.

The first answer to the OP question is obtain the power, torque and fuel cirves of the engine.

Only because at the same RPM it has higher power.

 

In other words, it is power that determines how fast you climb the hill, not torque.

 

OK, let’s take the torque out

0 x 4000. / 9549 = 0

Palmer spent $60m to ensure LNP elected and got the permit for his coal mine worth billions soon after. If it walks like a duck...

I pulled the Divisional results for this year's Federal Election

Clive had enough primary votes to possibly sway the results in Bass and Chifley, and most of the other winnning margins were in the 20,000 + votes, so he'd have only been picking up scraps in preferences.

I'd say his influence on the election was close to nil.

He was bagging both of the major parties, I'd call his campaign Institutional Advertising, no real message, just Clive, Clive, Clive, Clive ad nauseum. He's a marketer so he's smart enough to know that wouldn't get any real political traction, but it would raise his profile.

In most seats his candidates received about 3000 votes, about what you and I would get if we nominated, then sat back and didn't campaign.

I don't know where his coal mine is, but if it's in Queensland it would think it would be a Labor government approving the permit.

".......will be impossible to run the coal trains both ways at once"

"We'll use Autonomous trains" said Turbo. "electric trains so there will be zero emissions", and Arfagh Bahrein, The Captain and OneTrack nodded, and smiled, for this was the age of The Assertion.

Onetrack noticed a mutton bird sitting at the entrance to the tunnel and pointing east.................

The only thing I can imagine that would detract from its use, is that 9 times out of 10, the position where the clamp is required, is inaccessible, has limited room to manipulate any tool on the hose/pipe - and is usually on the underside of everything, entailing jacking up the equipment, or rolling in the dirt, to fit the clamp!

 

I have one of them sitting on my shadow board - been there for 20 years; I just buy new clamps.

I found it takes a lot of skill to use with anything other than stainless steel wire; a fraction of a turn this way and the wire snaps, a fraction of a turn that way and the hose blows off. You just get the skill perfected and either don't need it for 12 months by which time you've forgotten the touch and have to learn all over again, or you need to wind a different weight wire.

It has the access problems you mentioned.

However; I can see it being an excellent tool in a production line situation.

Stormwater from rooves and roads runs off faster than when the place was naturally wooded,/grassed so any retardation would be a return to the earlier situation rather than something new. Local flooding  would occur less often.. More water would soak into the ground  in an au naturelle situation. Less soil compaction gutters and paved areas. Nev

 

Got to your bathroom, turn the taps on in your basin, leaving the plug out. Notice that the basin is slowly filling, turn the taps off befor the basin overflows. A retarding basin takes time to fill rather than flowing the full stormwater force down the waterways, but it is only delaying the inevitable. When it's full the full stormwater force flows. It's one of the two most dangerous flood control methods in the world. In Melbourne there is a series of 22 basins coming down from the Dandenongs. If the top one overflows they go down like a pack of cards, and the people below are flooded out.

"Equal gearing" - referring to gearing shows you are talking about power. Equal gearing means equal RPM, and at equal RPM power scales linearly with torque.

 

Yes it does:

500 Nm x 2000 rpm/9549 = 104.7 kW

500 Nm x 4000 rpm/9549 = 209.4 kW,   so 100% increase in rpm = 100% increase in power = linear progression

This is what I meant in my example:

500 Nm x 2000 rpm/9549 = 104.7 kW

600 Nm x 2000 rpm/9649  = 125.67 kW, so at equal gearing 2000 rpm the higher torque engined vehicle climbs the hill faster.

But a vehicle with LOWER torque can pass it by changing down a gear and revving hard

500 Nm x 2000 rpm/9549  = 104.7 kW

300 Nm x 4000 rpm/9549  = 125.67 kW

Go to a drag strip and talk about a car's power in kilowatts and torque in Newton-metres. The rev-heads will direct you to the next village that's looking for an idiot.

 

Honestly, how do you visualise a kilowatt or a Newton-metre?

 

You’re kidding me????

Is this the "story of  decade"?

 

No, there are better stories than that.

All new housing here has to have water retaining pits, to help stop the deluge that causes the bad flooding of old.

Well that's the retarding basin concept; another subject for a wet year.

The theory is each property holds the bulk of its runoff and lets it flow down over days rather than hours and the rivers and drains don't overcap.

To do that in Victoria you need a dam about 65% of the house/shed size; no one has that; abject fail onjce the wet seasons come.

I am not scared of saying anything to anyone if I think they are putting them and there passengers in harms way by being a dick.

 

Keep up the good work Alf; most people say nothing and effectively just let them die.

........get them back in the tunnels where they should be.

"Maybe the working conditions are the problem" mused Turbo "tell you what, I'll get them back for a 51% share in the tunnelling venture".

"DONE!" said the Captain, thinking "we were broke anyway".

"let's go down and have a look"

The floor of the tunnel was hot and rancid, but they both continued on. The Captain, who was nervous at the best of times have a squeal as two big white eyes loomed ahead. They seemed to be rising and falling. Could this be a sea monster, another trick by Clive Palmer, Big Tunnel trying to shut them down. The eyes called out; "We H H H H H H H H H H H H H H H H "  It was like a steam train; the Captain grabbed Turbo and used him as a shield, the little coward. Then Turbo recognised the shape; it was Arfagh Bahrein, the sidekick of Mustafa Skrahtch.

"We've truck Coal!" Arfagh blurted out, and the Captain fainted; once again Turbo's sixth sense had....

"...we have to take into account the environment. Fill them in and there'll be no more mutton birds to........."

[Turbo advises NES readers, that like many people, he is only human, and unlike some other people around here admits that he has many children, you have to do something in Victoria. However he had a flash of inspiration and advises the shortly the Turbine Family Choir will be leaving for a world tour on the stage. Turbo had read about a family in Austria at the beginning of WW2 who sang their way to freedom. No title for the show yet but Turbo is thinking of calling it Sound of Music]

Nev, I reckon you and I are on the same line of argument. We aren't really in conflict, it's just that I'm say that without torque, you have no horsepower, and you are saying that without horsepower no work can be done. I fully agree with that. 

 

Either way, we both get to the point of having Force to apply to the propeller. 

 

You are correct OME.

An engine has to produce torque before anything happens.

Power or horsepower is simply torque with a time element added in.

Your formula is correct for horsepower..

The metric fprmula is: P = Mn/9549

where:

P=kW

M=Nm

n=rpm

0549 - coefficient

So for an engine with 245 Nm torque:

At 1000 rpm it will produce 25.66  kW

At 5000 rpm it will produce 128.27  kW

In motor vehicles:

A vehicle with the highest torque will climb a hill fastest with equal gearing

A vehicle with a smaller engine with less torque can pass that vehicle by shifting down a gear and developing more power at faster rpm

Over 80 km/hr on a flat road at a constant speed, power is the biggest factor for pushing the wind out of the way (and goes up exponentially with speed.

So they interchange in importance depending on the job.

In fact this pointless mission was rather similar to the time the NSW Government decided to empty Sydneys sewage into the ocean outside the Heads.

It wasn't long before Sydney Harbour filled with turds, so the Government decided to build a loooong pipe out to sea. This put the end of the pipe exactly into the fastest channel in to Sydney, and the pipe is listed as one of Australia's ten white elephants, along with the Aussat Satellite which Australia built and paid the US to launch before they realised there were no scientists smart enough to use it. Bob Menzies sent the people who designed it (who were also scientists), saying "fom time to time one has to do unpleasant duties; you can go to the Weather Bureau and forecast the weather for the 21st Century; that should keep you out of jolly trouble!; and you'll.....

Just an overlap  mistake.

Here's a photo of Groom Lake Nevada.

You are looking at the long runway for the U2 and CIA Oxcart (later released to USAF as Blackbird)

Right there below is Area 51 where some people allege that the remains of the 1947 Roswell spacecraft and aliens were taken.

If anyone wanted to hide anything this would be it.

I'm not going to go into it, but there are Satellite alternatives to Google Earth which don't rely on overlap photography.

That airfield will not be invisible, and could be monitored for activity yearly, monthly, daily, live etc
