Thermodynamics Mech3001 - Week 6 - Problem 2 (5.43)

5.43 Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 500° C and 4 MPa with a velocity of 80 m/s, and leaves at 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of steam is 12 kg/s. Determine: a) Change in kinetic energy b) Power output c) Turbine inlet area

Answers: (a) -1.95 kJ/kg, (b) 12.1 MW, (c) 0.0130 m2
