Please include any and all calculations. Please also mention which tables are referenced. Thanks A A Rankine cycle with reheat and superheat is shown in Fig. A The pressure in the steam generator is bar ppmathrmbar the intermediate pressure at the exit of the first stage of the turbine is bar pp bar and the pressure in the condenser is mathrmbarleftppmathrmbarright The working fluid is water mass flow rate, dotmmathrm~kgmathrms The turbine both stages and the pump operate adiabatically. At the exit of both stages of the turbine, the working fluid is saturated vapor points and At the exit of the condenser point the working fluid is saturated liquid. Do the following analysis:
a What is the state of water at point if the temperature is TcircmathrmC
b Determine the specific enthalpy and the specific entropy of the working fluid at point
c Determine the isentropic coefficient of the first stage of the turbine.
d If the expansion of the working fluid in the second stage of the turbine is isentropic determine the state of the working fluid at point as well as its temperature and specific enthalpy
e If the isentropic coefficient of the pump is determine the specific enthalpy of the working fluid at point
f Determine the state of water at point Calculate the temperature of the working fluid at point Verify, that the compression of the working fluid causes an increase in the entropy generation, by applying nd Law for open systems around the pump and determining the rate of entropy generation in WK
g Sketch the entropytemperature diagram of this cycle
h Determine the power of the turbine in kW the power spent on the pump in kW and the net power output of the cycle in kW
i Determine the rate of heat, dotQi n added to the steam generator in kW and the rate of heat, dotQtext out rejected from the working fluid to the condenser cooling water in kW Verify your result for the net power output of the cycle in h Determine the thermal efficiency of the cycle.
j Determine the mass flow rate of the condenser cooling water, in mathrmkgmathrmh if cooling water enters the condenser at circmathrmC and exits at circmathrmC
