Air is used as the working fluid in a simple ideal Brayton cycle that has a pressure ratio of 10, a compressor inlet temperature of 300 K, and a turbine inlet temperature of 1000 K.
(a) 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 100%.
(b) Draw a T- s diagram of the process.
