Consider an ideal Rankine cyle steam power plant with reheat. Superheated vapor enters the first turbine stage at 10 MPa and 480 C. The steam expands through the first turbine stage to 0.7 Mpa and then is reheated to 480 C. The condenser pressure is 6 kPa. Determine the following:
I) the heat added in the boiler (kJ/kg)
II) the thermal efficiency
III) the heat removed in the condenser (kJ/kg)
