Air enters the compressor of an air-standard Brayton cycle at 100kPa, 300K, with a volumetric flow rate of 5m^3/s. The turbine inlet temperature is 1400K. The compressor and Turbine both have isentropic efficiencies of 88%. The pressure ratio is 6.
Draw a T-S diagram and label all the states.
Using the cold-air standard assumption Find the :
a) Thermal efficiency versus pressure ratio.
b) Back work ratio versus pressure ratio.
c) Net power developed in kW versus pressure ratio.
