Boiler Problem 2 - Steam Power Cycle with Reheat and Irreversibility A steam power plant operates on the reheat Rankine cycle with irreversibilities at steady-flow conditions. Steam enters the high-pressure turbine at 12.5 MPa and 550C at a rate of 8 kg/s and leaves at 2 MPa. Steam is then reheated at constant pressure to 450C before it expands in the low- pressure turbine. The isentropic efficiencies of the turbine and the pump are 85 percent and 75 percent, respectively. Steam leaves the condenser as a saturated liquid at 15 kPa. Assume that the turbines are adiabatic and the changes in kinetic and potential energy are negligible. Please answer the following: a. As you solve this problem, complete the values in the table below. Assume that the Turbine Condenser Pump pressure drops are negligible. Some of the values from the problem statement are already entered.

Sketch the cycle on a T-s diagram. Indicate the values for T (C) and s (kJ/kg-K) for the actual states. c. Determine the power that needs to be supplied to the pump, in kW. d. Starting with the general energy balance that corresponds to the pump and turbines, compute the net power output for the cycle, in kW. Show your equations in literal form before substituting numerical values. e. Compute the thermal efficiency for this cycle. f. Compute the rate of entropy generation for this cycle, in kW/K. Show your equations in literal form before substituting numerical values. (Hint: on every process where there is heat transfer across a boundary at temperature Tb, there will be entropy transfer due to heat transfer crossing a boundary at temperature Tb. If you identify that being the case in any part of your solution, please assume a reasonable boundary temperature so that you can compute the entropy transfer due to heat transfer.)
