Cadman’s Hydrostatic Displacement Engine

[Cadman]

Hi Brad,

You may have a point. This is going to require an experiment to sort out.

If you took a 6" ID tube 5 ft tall closed at the bottom, filled it with 7" of water, and dropped a 5.95" x 40" 17 lb slug into it, I just can't believe that the slug would float and not sink to the bottom of the bucket even if the slug had a 1.5" hole in it.

Ahh, I think I may have it. We are not taking atmospheric pressure into account.?
Well, we'll see what's what. The proof is in the pudding, eh?

Regards,
Cadman

Your pipe inside a pipe is a good test.
I think you will be surprised at the result.

Like you say,absolute answers are found by testing the actual device.

Thank you Graham!!

If the volume of the displacement tube weights more than the equal volume in water (it sinks in a tub full of water) then it works ...... Only it don't work with that much weight because the displacement tube could just be water instead!
