when 229j of energy supplied as heat at constant pressure to 3 mol co2 gas the tempreture of the sample increases by 2.06k. calculate the molar heat capacity at constant volume and at constant pressure of gas ?

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
