Mechanical Engineering

Consider a simple Brayton cycle using air as the working fluidwith properties assumed constant and evaluated at room temperature(300 K). Conditions at the compressor inlet are T1 = 25°C and P1 =200 kPa. The pressure ratio is 11 and maximum cycle temperature is750°C. Answer the following (a) Compute the back?work ratio andcycle efficiency assuming both the turbine and compressor areisentropic (b) Compute the same quantities assuming only theturbine is isentropic while the compressor has an isentropicefficiency of 75% (c) Compute the same quantities assuming only thecompressor is isentropic while the turbine has an isentropicefficiency of 75%

Please show all work, assume ideal gas and cold air assumptionsand please write legible. Thanks
