Problem 2 Five kilograms of air initially at 15 C and 100 kPa is compressed until the pressure is 650 kPa and the temperature is 270 C. Calculate the entropy change during this process assuming ideal-gas behavior and constant specific heats. Problem 3 A large steam turbine take in 5 kg/sec of steam at 600 C and 12 bar and rejects it at 0.5 bar, and is supposed to
