A power plant is analyzed as a simple Rankine cycle with a boiler operating at a pressure of 7 MPa. Steam leaves the boiler and enters the turbine as a superheated vapor at a temperature of 500 oC. The condenser operates at a pressure of 10 kPa. Sketch the cycle on a Pv and a Ts diagram and then determine:
a. The temperature in the condenser: T1 = T4
b. The heat added in the boiler, per kg of steam: q2-3
c. The work done by the turbine, per kg of steam: w3-4
d. The work done by the pump, per kg of steam: w1-2
e. The thermal efficiency of the power plant: h
