WebSo the gas pressure on the high pressure side is changing slowly, and the gas remaining on the high pressure side is doing work on the gas ahead of it to force the gas ahead of it through the valve. It is doing this work by expanding adiabatically and reversibly against the back pressure of the gas ahead of it. WebMay 14, 2024 · For an irreversible expansion process, a crude approximation to the force exerted by the gas on the piston (where the work is done) can be provided by the equation F A = P e x t = n R T V − k V d V d t where P e x t is the force per unit area of the piston on the gas and the constant k is proportional to the gas viscosity.
