Thermodynamics Mech3001 - Week 7 - Problem 4 (7.112)

Steam enters a steady flow adiabatic turbine at 500°C, 8 MPa with mass flow rate of 3kg/s. The steam leaves the turbine at 30 kPa. The isentropic efficiency of the turbine is 90%. Neglecting the kinetic energy of the steam, determine (a) temperature of the turbine exit and (b) power output of the turbine

Answer: 69.1°C, 3054 kW
