Show the inlet and exit states on a P-v diagram.
Steam flows steadily through an adiabatic turbine
Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500°C, and 80 m/s, and the exit conditions are 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of the steam is 12 kg/s. Determine a. (3) Change in kinetic energy (-23.4 kJ) b. (4) Power output (12.12 MW) c. (3) Turbine inlet area (0.012966 m2)

Refrigerant 134a enters a turbine with a mass flow rate of 12 kg/s at 54°C, 3 MPa, while the velocity is negligible. The refrigerant expands in the turbine to a saturated vapor at 400 kPa where 10 percent of the steam is removed for some other use. The remainder of the refrigerant continues to expand to the turbine exit where the pressure is 5 kPa and quality is 75 percent. If the turbine is adiabatic, determine the rate of work...
