Main Question or Discussion Point
If I have a bladder (or balloon) that is charged with 300# of a nitrogen gas at a normal atmospheric pressure outside the bladder, and I then enclose the bladder and subject that bladder to a liquid pressure of 25# on it's outside surface area but inside the enclosure. Assuming a constant temperature, does the inside pressure of the bladder increase due to the 25# of liquid pressure, or does it take more than 300# of liquid pressure on it's outside surface area to get the pressure inside the bladder to increase? This is not a homework problem, but a problem with a system I am trying to understand at my work place. Thanks in advance for any insight you can provide.
