Compressed liquid water with an enthalpy of 100.0 kJ/kg entered a boiler which maintains the pressure and temperature at 2500 kPa and 500 °C respectively. Upon leaving the boiler, the superheated steam entered a turbine where it exited at a temperature of 45 °C and enthalpy of 2000 kJ/kg. The mass flow rate is 1000 kg/s. (A) Determine the heat added to the boiler in Watts in order to turn the compressed liquid water into superheated steam. (B) Determine the work output of the turbine in Watts. (C) Indicate the condition of the fluid exiting the turbine if it is saturated and the quality.
