Question on D-FAlso why not assume that P1=P4? 1. A combined cycle power plant has the operating points shown in the figure below. Airenters the compressor of the gas cycle at 14.7 psi (atmospheric pressure) and 60ʻF with avolumetric flow rate of 40,000 ft/min. The compressor operates with a pressure ratio of 11and an isentropic efficiency of 87%. The air enters the turbine at state 3 at 2140°F, and theturbine operates with an isentropic efficiency of 90%. The air exiting the turbine passesthrough the interconnecting heat exchanger is exhausted to the atmosphere at 400*F.CombustorCias turbineCompressorTurhinegasAir inletExhaustHeat-recoverysteam generatorTurhineVaporсуcle11PutmpCondenser10CoolingwaterWater enters the turbine of the vapor cycle at 1000 psi and 900°F.

The mass flow rate of water, in Ibm/h,c. The mass flow rate of cooling water passing through the condenser, in Ibm/h, if it issupplied from the cooling tower at 55*F and returns at 80*F,d. The rate at which energy must be added to the system by heat transfer, in Btu/h,e. The net power output of the system, in Btu/h, andf. The thermal efficiency of the cycle.
