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. QUESTION 1 Using the property tables for both the inlet and outlet of the pump, determine the enthalpy in kJ/kg of the pump outlet. Report your answer to two decimal places using rounding. QUESTION 2 Report the amount of heat added, in kJ/kg, in the boiler before the high-pressure turbine to one decimal place using rounding. QUESTION 3 Report the amount of work produced in the high- pressure turbine, in kJ/kg, to one decimal place using rounding.
