Question

Enthalpy data is given for a regenerative Brayton cycle with intercooling and reheating. The cycle
produces a net power of 14??. Calculate
a) the mass flow rate of air in ??⁄?
b) heat rejection rate of the intercooler in ??
c) the back work ratio
d) the thermal efficiency
e) the second law efficiency if the cycle receives heat from a medium at a temperature of 1600? and
rejects heat to a medium at a temperature 290?.

Enthalpy data is given for a regenerative Brayton cycle with intercooling and reheating. The cycle
produces a net power of 14MW. Calculate
