Work Problem 8.13, retaining all quantities except with the following turbine exit pressure:
a) 50 kPa
b) 30 kPa
c) 20 kPa
d) 10 kPa
Rework Problem 8.13
An ideal Rankine power cycle is shown in Fig. 8.31. Steam leaves the steam generator at 4 MPa and 500°C with a mass flow rate of 8 kg/s. The steam leaves the turbine at 40 kPa. Sketch the cycle on a T-s diagram; then calculate:
i) The power output of the turbine
ii) The rate of heat loss from the condenser
iii) The pump horsepower requirement
iv) The rate of heat addition by the boiler
v) The cycle efficiency
