4. (Without regeneration) Air enters the compressor of a Brayton cycle at 100 kPa, 300K with a mass flow rate of 6 kg/s. The compressor pressure ratio is 10, and the turbine inlet temperature is 1400K. The turbine and compressor each have isentropic efficiencies of 80%. For k = 1.4, determine: (a) the thermal efficiency of the cycle (b) the back work ratio (c) the net power developed in kW The back work ratio is the ratio of the compressor work to the turbine work.
