The net power produced by the cycle is 5 MW. The pressure ratio across the compressor is 8:1. Air enters the compressor at T1 = 300 K, P1 =100 kPa and is heated by an external heat exchanger to T5 =1200 K before entering the turbine. Ten percent (10%) of the mass entering the compressor is removed from the compressor at 500 kPa. The working fluid is air with constant specific heats and has properties as follows: Cv = 0.718 kJ/(kg-K), Cp = 1.005 kJ/(kg-K), R = 0.287 kJ/(kg-K), k = 1.4 (A) Sketch a T-s diagram for the cycle. (B) Determine the temperature at which the removed air leaves the compressor, in K. (C) Determine the total mass flow rate of the air into the compressor at 300 K, 100 kPa, in kg/s.
