Steam enters the high-pressure turbine of an ideal reheat Rankine cycle at 10 MPa and 500°C. The low-pressure turbine inlet admits steam at 1 Mpa. Assume that the pump inlet is a saturated liquid at 10 kPa and that 80 MW of power is produced overall. 1. Using the property tables for both the inlet and outlet of the pump, determine the enthalpy in kJ/kg of the pump outlet. 2. Report the amount of heat added, in kJ/kg, in the boiler before the high-pressure turbine to one decimal place using rounding. 3. Report the amount of work produced in the high-pressure turbine, in kJ/kg, to one decimal place using rounding.
