wow hans, you impress me mate!

No problem Mike,

Just send us your credit card details and we will send you your official resident spook ID card issued by Langley.

Then you can go and harass persecuted scientists like Mr. Tseung and get paid for it. You will also be eligible for a Nigerian grant of 25.000.000.00 Great Britain Pounds. I will instruct our fiduciary agent and executive CEO right now.

Long live the suppression of revolutionary science.

Hans von Lieven       Agent.......well, you know.

Dear Hans,

Brilliant logic and good scientific thinking.

Unfortunately, you never did the experiment.  If you did the actual experiment, you would have observed:

(1)   The US$1.00 Pump could not pump air at a very high rate.  It was ?burst and stop?.  That was the reason why we used two to get a more steady flow.

(2)   You simply ignored the action of the one-way valves.  The one-way valves allowed air+water to go up and NOT down.

(3)   Let us examine the air+water mixture inside a section of the pipe in between two one-way valves. The pressure of the air+water above had no effect on the pressure of this section as the top one-way valve blocked it.  The pressure of air+water exerted on the bottom valve was (in the worse case) pressure of air trapped + pressure of the partial water column.

(4)   In reality, on steady flow, the air+water in the pipe was made up of many water bubbles.  They did not have the same size but there would be multiple of them inside the pipe.

(5)   The correct physics calculation of the pressure inside the section mentioned in (3) should be approximately the pressure required to open the one-way valve with the air+water inside.  That was a function of the type of one-way valve and spacing of two valves used.  If the one-way valves were perfect, each section of pipe should have approximately the same pressure.  The total back-pressure at the air pump was NOT related to the height of the total water column!  It would just be the pressure required to open the one-way valve.

(6)   When we did the experiment, the US$1.00 valves were not perfect.  If we stopped pumping, we could see water slowly accumulate at the bottom.  The bottom section (or a particular bad section) would have no air.  It would have water only.  Then the back-pressure greatly increased and we were not able to pump anything up any more.

(7)   The initial action was to get the whole clear plastic tube with the one-way valves down and let the air+water flow out in the direction of the one-way valves.

(8 )   Later, we ensured that before the end of each experiment, we turned off water from the lower tank first and kept pumping until the pipe was full of air.

I was going to bet US$1 million that I could get some water to even the 100th floor.  However, I believe the CIA did not pay you that much.  So I am quite willing to bet a US$10 meal when and if we meet.  I shall describe how I would do it in a following post.  Thank you for the meal in advance.

Saying someone is a liar without doing the experiment first results in paying for a US$10 meal.  Not a bad deal for a Physics Lesson not taught at Universities.

No good Lawrence,

Nice try but still rubbish. The one way valves just allow the water to reflux and fill the pipe much more quickly.

And you are right, I have not done this specific experiment, what I have done though is designed, repaired and built many such systems in the past, predominantly for moving things like grain and woodchips and so forth.

The principles of this sort of system are well known to me and are attested by the many devices along those lines I have built and maintained, many of which are still in operation.

You are talking crap and you know it!

EDIT:  Ps. I am not talking about theoretical knowledge here predominantly but of over 40 years in the field mainly as a troubleshooting engineer.

Hans,

I am going to tell you why you will be paying for the US$10 meal.

The experiment done was as follows:
(I actually took part in this section of this experiment.)

(1)   We purchased a roll of clear plastic tubing that would fit the outlet of the US$1.00 valve.  (Inner diameter = 7 mm) Each roll was 100 meters. (paid for by Tseung)

(2)   We went up to the 34th floor and let the tube down.  We had a strong guy holding the upper end of the tube. (Tseung was NOT the strong guy.)

(3)   At the ground floor, we used the US$1.00 beach pump to pump air only.  We detected that air actually came out from the upper end with a tissue paper. (Tseung and many others did the pumping.  It was a piece of cake.)

(4)   Then we introduced the set up with the lower water tank but no one-way valves in the tube.  Water was introduced/ dripped very slowly.  Water droplets were seen going up the tube.  (The tube was clear plastic.)

(5)   At the top floor, the tissue paper got wet.  Thus we were 100% sure that water did arrived at the top.  We did not care about the flow rate then. (Tseung and others took the lift to go up to check.  Tseung did not need the exercise!)

Water got to the 34th floor.  Have I won the bet yet?  If not, I shall continue the story.

Lawrence Tseung
Winning a bet is easy if you have already done the experiment.
