Air enters the compressor of a gas power cycle at 100kPa, 300K, and a volumetric flow rate of 5 m3/s. The compressor pressure ratio is 10. The turbine inlet temperature is 1400K. The turbine and compressor each have an isentropic efficiency of 80%. Assume variable specific heats.
Determine:
a) the thermal efficiency of the cycle
b) The back work ratio
c) the net power developed by the cycle in kW.
