Thank you for the reply 256bits. I was relating it to the need of an incompressible fluid in hydraulics. If this incompressible fluid is replaced by a compressible one, wouldn't it make a diffrence on the force. So I still am not completely convinced with the
If an inert gas is used to force piston with a Pressure say P (Assume the volume of gas to be sufficiently large). I would like to know the following: (consider piston to be horizontal)
1) If say one puts a small volume of a hydraulic fluid in front of the piston. Keeping the same pressure of...
