Prоblem 2 (15 pоints) Wаter is used аs the wоrking fluid in а simple Rankine cycle. The water enters the boiler and is heated isobarically to 5 MPa and 500°C (state 3). There is heat transfer and pressure drop in the piping connecting the boiler outlet to the turbine inlet (state 4). The water exits the turbine at 275 kPa (state 5) and leaves the isobaric condenser as a saturated liquid (state 1). Both the pump and the turbine are adiabatic. The pump is also reversible, but the turbine has an isentropic efficiency of 95%. The mass flow rate of water through the power-generating system is 80 kg/s. You need not perform any mass balances while working through this problem. You may simply use the fact that is the same through each device since they all have one inlet and one outlet and they are all connected in series. The heat transfer rate from the water to the surroundings as it flows through the piping connecting the boiler outlet to the turbine inlet is measured to be 8840 The pressure into the turbine is measured to be 4.5 MPa. Perform an energy balance on the piping to determine the temperature of the steam entering the turbine (state 4). Do not perform any interpolation in determining this temperature; just pick the table value that most closely matches your calculations. Start your analysis by identifying an appropriate system, write down the general versions of any balance equations you need, and clearly identify any assumptions you use and how they affect your analysis. Fill in the missing in formation in the table below. Show all your work/justifications and write your final answers in a table like the one shown below. If you already showed the relevant work in part (A), indicate so by writing “work performed in part (A).” You were previously told not to interpolate for state 4, but you should interpolate for any other state if necessary. State Specific Enthalpy (kJ/kg) Specific Entropy (kJ/kg·K) 1 (pump inlet) 548.86 1.6408 2 (boiler inlet) 3 (boiler outlet) 3434.7 6.9781 4 (turbine inlet) 5 (turbine outlet) Calculate the thermal efficiency of this cycle. Any heat or work terms you use to answer this question must come from an analysis that identifies an appropriate system, starts with general versions of any balance equations you use, and clearly identifies any assumptions you use and how they affect your analysis.
