I have been trying to find out how to calculate a number of things in a system involving liquid and gas.
In the attached diagram there is a U-bend with gravity acting down on it. If one side is sealed with a plunger and the other side is filled with a fluid (L) we would end up with the trapped gas (G). Assuming the plunger remained stationary (held in place). I would like to calculate:-
1) The Pressure of G and also the volume by which it would be compressed. (I presume this will involve the densities of L and G and the mass of X?)
2) The force required to push the plunger down and move the gas and liquid around the tube. (would this just be the force required to lift L?)
My degree is in Zoology! and I really have trouble remembering my GCSE Physics so any help would be FANTASTIC, even if its just directed reading material.
Thanks
PS. Not sure if this post belongs in the mechanics section
