Calculate Heat transfer through cylinder wall:
Calculate change in entropy and heat transfer through cylinder walls, if 0.4m^{3} of a gas at the pressure of 10bar and 2000C expands by the law PV1.35 = Constant. At the time of process there is loss of 380KJ of internal energy. (Take CP = 1.05KJ/kg k and CV = 0.75KJ/kgK)
Sol: ds = ?
