Steam enters a converging-diverging nozzle at steady state with P1 = 40bar T1 = 400°C and a velocity of 12m/s. The steam flows through the nozzle with negligible heat transfer and no significant change in potential energy. At the exit P2 = 15bar and the velocity is 700 m/s. The mass flow rate is 2.5 kg/s. Determine the exit area of the nozzle in m2

Steam at 250oC and 1 MPa enters a compressor at a steady rate of 2 m3 /s with a velocity of 0.1 m/s. The device uses 6500 kJ/s of energy to compress the steam to a temperature of 500oC and a pressure of 4 MPa. Assuming that this device is adiabatic and that you can ignore potential energy changes, calculate the steam velocity and mass flow rate at the exit of the compressor.
