Air enters the compressor of a cold air-standard Brayton cycle with regeneration at 90 kPa, 293 K, with a mass flow rate of 6 kg/s. The compressor pressure ratio is 10, and the turbine inlet temperature is 1300 K. The turbine and the compressor each have isentropic efficiencies of 85% and the regenerator effectiveness is 85%. Assume constant specific heats, take k = 1.4 and CP = 1.005 kJ/kgK. 3.2.1 Represent the cycle on a T – s diagram. Calculate:

Question
Air enters the compressor of a cold air-standard Brayton cycle with regeneration at 90 kPa, 293 K, with a mass flow rate of 6 kg/s. The compressor pressure ratio is 10, and the turbine inlet temperature is 1300 K. The turbine and the compressor each have isentropic efficiencies of 85% and the regenerator effectiveness is 85%. Assume constant specific heats, take k = 1.4 and CP = 1.005 kJ/kgK.
3.2.1 Represent the cycle on a T – s diagram. Calculate:
-
3.2.2 the thermal efficiency of the cycle,
-
3.2.3 the back work ratio, and
-
3.2.4 the net power developed, in kW.
