A gas turbine power plant operates on the simple brayton cycle between the pressure limits of 100 and 800 kPa.Air enters the compressor at 30 C and leaves at 330 C at a mass flow rate of 200 kg/s.The maximum cycle temperature is 1400k.During operation of the cycle,the net power output is measured experimentally to be 60 MW.Assume constant properties for air at 300 K with Cv=0.718 kJ/kg.K, Cp=1.005 kJ/kg.K, R=0.287 KJ/kg.k
k=1.4
a-Determine the isentropic efficiency of the turbine for these operating conditions.
b-Determine the cycle Thermal efficiency.
