What is the lowest maximum cycle temperature at the engine

Reference no: EM13307060

a gas turbine engine based on a brayton cycle uses air as the working fluid that produces 5mw net power output. the air enters the compressor at 27 c and 100kpa.the pressure ratio across the compressor is 9 and the maximum temperature is 827c.the turbine and comprssor processes are adiabatic with turbine efficiency of 90% and a compressor efficiency of 85%. you may assume ideal gas with constant speific heat
cp=1.0035 kj/kg-kand k=1.4

a- determine the cycle thermal efficiency

b- what is the lowest maximum cycle temperature at which the engine will run no net power out
