Basic components and T-s process diagram for an ideal Rankine cycle.
An ideal Rankine cycle uses water as a working fluid, which circulates at
a rate of 80 kg/s. The boiler pressure is 6 MPa, and the condenser pressure
is 10 kPa. The water enters the turbine at 600°C and leaves the condenser
as a saturated liquid. Assume that heat is transferred to the working fluid
in the boiler from a reservoir at 1400 K and that the fluid in the condenser
rejects heat to the surroundings at 25°C. Calculate the following quantities:
a. The power required to operate the pump
b. The heat-input rate to the water in the boiler
c. The power developed by the turbine
d. The heat-rejection rate in the condenser
e. The thermal efficiency of the cycle
