Work Problem 8.17, retaining all quantities except with the following turbine exit pressure:
a) 10 psia
b) 8 psia
c) 4 psia
d) 2 psia
Rework Problem 8.17
An ideal Rankine power cycle shown in Fig. 8.32 has a boiler that produces steam at 600 psia and 900°F with a mass flux of 18 lbm/s. The steam leaving the turbine has a pressure of 10 psia. Sketch this cycle on a T-s diagram and 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
