A cold-air standard closed Brayton cycle operates with a compressor pressure ratio of 14. Air enters the compressor at 14 psi. The minimum and maximum temperatures are 520 °R and 2500 °R, respectively. The isentropic efficiencies of the compressor and turbine are 83% and 87% respectively. The net power developed is 5.0 x 106 BTU/h. Evaluate specific heats at ambient temperature of 520 °R. Hint! You do not necessarily need to solve parts b-e in order! a. Draw the process on a T-s diagram. b. What is the mass flow rate of the air entering the compressor in lbm/hr? c. What is the volumetric flow rate of the air entering the compressor in ft3/min?d. What are the temperatures at the compressor and turbine exits in °R? e. What is the thermal efficiency of the cycle?
