Question
Can someone provide a detailed solution to this problem please thank you . A Rankine cycle with reheat and a closed feedwater heater (with its drain cascaded to the condenser) has 150 kg/s of superheated steam at 3000 psia and 1 100 entering the turbine. Steam is extracted at a pressure of 1000 psia and sent to the reheater, where it returns to the turbine at 1050 °F. The feedwater temperature leaving the closed feedwater heater is equal to 10 °F below the temperature of the steam leaving the turbine and being sent to the closed feedwater heater. The extracted water in the drain of the closed feedwater heater has a quality of zero. The condenser pressure is 2 psia. The isentropic efficiency of the turbine is 0.78 and of the pump is 0.68. Compute the net power produced, the mass flow rate of the steam extracted and sent to the closed feedwater heater, and the thermal efficiency of the cycle for the following pressures of the extracted steam directed toward the closed feedwater heater from the turbine: (a) 50 psia. (b) 450 psia. (c) 900 psia. Please discuss the differences among the three casesExplanation / Answer
In this problem the values of enthalpy at various points should have to be given or in question you have to mention about the usage of steam table or mollier charts, thats why unable to solve the question.
