[answerhappygod]

Air enters the compressor of an ideal air standard Brayton cycle
at 195 kPa, 290 K, with a volumetric flow rate of 5 m3/s. The
compressor pressure ratio is 8. The turbine inlet temperature is
1500 K. The compressor has an efficiency of 90% and the turbine has
an efficiency of 75%.
a) Determine the thermal efficiency (ηth,Brayton).
Express your answer to three significant figures.
b)Determine the net power output (W˙net).
Express your answer to six significant figures and include
appropriate units.
c)Determine the back work ratio.
Express your answer to three significant figures.(%)
