Problem $5\mathrm{.}7$

A Rankine steam power generation cycle is operating under the following conditions: $$

Steam leaves the boiler $($and superheater$)$ at $20$ bar and $700C.$ The condenser produces a saturated liquid at $0\mathrm{.}2$ bar. The steam lines are wellinsulated, the turbine and pump operate reversibly and adiabatically. Some of the work generated in the turbine is used to drive the pump. Determine:

a$)$ Net work obtained per kg steam

b$)$ Heat discarded in condenser

c$)$ Fraction work from the turbine used to drive the pump

d$)$ Heat absorbed in the boiler

e$)$ Engine efficiency. Compare with Carnot efficiency.
