Air is used as the working fluid in a simple ideal Brayton cycle that has a pressure ratio of 12, a compressor inlet temperature of 300 K, and a turbine inlet temperature of 1000 K. Determine the required mass flow rate of air for a net power output of 70 MW, assuming both the compressor and the turbine have an isentropic efficiency of (a) 100 percent and (b) 85 percent. Assume constant specific heats at room temperature.

Air is used as the working fluid in a simple ideal
Brayton cycle that has a pressure ratio of 12, a compressor
inlet temperature of 300 K, and a turbine inlet temperature
of 1000 K. Determine the required mass flow rate of air for
a net power output of 70 MW, assuming both the compressor
and the turbine have an isentropic efficiency of (a) 100
percent and (b) 85 percent. Assume constant specific heats at
room temperature.
