Question
Could anybody solve this problem ... ?ASAP?Steam leaves a power plant steam generator at500lbf/in2,650F, and enters the turbine at490lbf/in2,625F. The isentropic turbine efficiency is88%, and the turbine exhaust pressure is 1.7 lbf/in2.Condensate leaves the condenser and enters the pump at110F,1.7lbf/in2. The isentropic pump efficiency is 80%,and the discharge pressure is 520lbf/in2. The feedwaterenters the steam generator at 510lbf/in2.,100F.Calculate the thermal efficiency of the cycle and the entropygeneration of the flow in the line between the steam generator exitand the turbine inlet, assuming an ambient temperature of77F.
