NO INTERPOLATION REQUIRED

Air enters an adiabatic turbine at 1000 kPa and 1625 degrees C (state 1) with a mass flow rate of 5 kg/s and leaves at 100 kPa the isentropic efficiency of the turbine is 85%. Neglecting the kinetic energy change of the steam, and considering variable specific heats, determine:

a. the isentropic power of the turbine

Isentropic power in kW

b. the temperature at the turbine exit

temperature at exit in degrees C

c. the actual power output of the turbine

Actual power in kW

d. the rate of entropy generation in the turbine

Rate of entropy generation in kW/K
