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.

A 1.2 m3 rigid tank initially contains steam at 8 MPa and 400 ◦C. The steam slowly comes out through a hole at the bottom until the pressure drops to P0 while keeps the temperature constant. Making the pertinent considerations determines: a) the heat transferred, in kJ when P0 = 2 MPa. b) graph the heat transfer, in kJ, versus P0 from 0.5 to 8.0 MPa

Steam at 4.5 MPa and 500 C enters the turbine with a velocity of 60 m/s and its mass flow rate is 5,000 kg/h. The steam leaves the turbine at a point 3m below the turbine inlet with a velocity of 350 m/s. The heat loss from the turbine is 100,000 kJ/hr and the shaft work produced is 950hp. A small portion of the exhaust steam from the turbine is passed through a throttling valve and discharges at atmospheric pressure....
