Water is the working fluid in a vapor power plant. superheated steam leaves the steam generator at 8.2 mpa, 540 ∘c, and enters the turbine at 7.5 mpa, 500 ∘c. the steam expands through the turbine, exiting at 8 kpa with a quality of 94%. condensate leaves the condenser at 5 kpa, 30 ∘c and is pumped to 9 mpa before entering the steam generator. the pump efficiency is 80%. part a a) determine the net work per unit mass of steam flow.

b) determine the heat transfer per unit mass of steam passing through the boiler

c) determine the thermal efficiency.

d) determine the heat transfer per unit mass of steam passing through the condenser.
