Question

# For the Rankine cycle shown, the pump takes in a saturated liquid at 100

kPa. The turbine inlet is 8 MPa and

600°C. The turbine has an isentropic

efficiency of 85%.

a. Find the quality and temperature of the steam exiting the turbine.

b. Find the thermal efficiency of the system.

c. If the pump power is 50 kW, find the rate of heat addition to the boiler.

d. If the cooling water may only change by 30°C, find the required mass

flow rate required.

e. Draw the T-s diagram
