Q1: Steam enters a nozzle at 15 m/sec at 0.6 mPa and 700oC and leaves at 0.2 mPa at 400oC,the velocity (m/sec) at the exit is most nearly (assume no heat loss). NOTE: 1 kJ/kg = 1000 m2 /s
Q2: How much work (kJ) is done by an engine which contains 1 kg of water that goes from 0.6MPa, 900oC to 0.10 MPa, 150oC if 1,000 kJ of heat is added?
Please solve both questions. Thank you
