A piston-cylinder device initially contains 0.4 m3 of air (to be treated as an ideal gas) at 100 kPa and 80 oC. The air is now isothermally compressed to 0.1 m3 . The work done during this process is ________ kJ. Gate-20161 AnswerAdiabatic work of 200 kJ is done on ideal gas of mass m = 1 kg (Cv=1000 j/kgk ), which is stored in a rigid container at a pressure of 100 kPa and temperature 300 K.1 AnswerA certain amount of an ideal gas is initially at a pressure P1 and temperature T1. First, it undergoes a constant pressure process 1-2 such that T2 = 3T1/4. Then, it undergoes a constant volume process 2-3 such that T3 = T1/2. The ratio of the final 1 AnswerA double acting hydraulic cylinder has a rod diameter equal to one - half the piston diameter. If the system pressure is maintained constant, t he ratio of load carrying capacity of extension stroke to that of retraction stroke is.
