Air enters the compressor of an air-standard Brayton cycle with
a volumetric flow rate of 60 m3/s at 0.8 bar, 280 K. The
compressor pressure ratio is 17.5, and the maximum cycle
temperature is 1950 K. For the compressor, the isentropic
efficiency is 92% and for the turbine the isentropic efficiency is
95%.
Determine:
(a) the net power developed, in kW.
(b) the rate of heat addition in the combustor, in kW.
(c) the percent thermal efficiency of the cycle.
