Entropy change of Gas Turbine
A gas turbine is used to harvest kinetic energy from superheated vapor and convert it into
electricity through a generator. In a power plant, water is heated to a superheated vapor state
before entering the turbine. The pressure and temperature of the superheated vapor are 10.0
MPa and 750 °C. The superheated vapor enters the turbine at a steady rate of 0.5 kg/s.
Consider the isentropic efficiency of the turbine is 88%, determine:
1) The properties of the fluid at the turbine outlet if the exit pressure is at 800 kPa
a. Enthalpy
b. Temperature
c. State
2) The power output of the turbine
