University Of California, Davis Operations And Supply Chain Management Assignment Help - The power plant

Question - The power plant shown in Fig. 11.40 combines a gas-turbine cycle and a steam turbine cycle. The
following data are known for the gas-turbine cycle. Air enters the compressor at 100 kPa, 25C, the
compressor pressure ratio is 14, and the isentropic compressor efficiency is 87%; the heater input
rate is 60 MW; the turbine inlet temperature is 1250C, the exhaust pressure is 100 kPa, and the
isentropic turbine efficiency is 87%; the cycle exhaust temperature from the heat exchanger is 200C.
The following data are known for the steam-turbine cycle. The pump inlet state is saturated liquid at
10 kPa, the pump exit pressure is 12.5 MPa, and the isentropic pump efficiency is 85%; turbine inlet
temperature is 500C and the isentropic turbine ef ...Read More ficiency is 87%. Determine
a. The mass flow rate of air in the gas-turbine cycle.
b. The mass flow rate of water in the steam cycle.
c. The overall thermal efficiency of the combined cycle. ...Read Less
