A gas turbine engine based on the brayton cycle uses air as the working fluid that produces 5MW net power output. The air enters the compressor at 27 degrees C and 100kPa. the pressure ratio across the compressor is 9 and the maximum temperature is 827 degrees C. the turbine and compressor process are adiabotic with a turbine efficiency of 90% and a compressor efficiency of 85%. you may assue ideal gas with constant specific heat, Cp = 1.0035 kJ/kg-K 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 output)?
