A power plant operates with a high-pressure steam of 50 bar and has a boiler exit temperature of 600 C. The exhaust steam from a turbine has a quality of 95%, is then condensed into saturated liquid water at 10 kPa, and finally pumped into the boiler. The efficiency of pump is 0.80. Using steam table and/or Mollier diagram, estimate: (1) The efficiency of the turbine. Sketch the expansion process of the turbine in Mollier diagram below. (2) The work supplied into the pump. (3) The amount of heat transfer in the boiler. (4) The amount of heat transfer in the condenser.
