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
