Question

A heat engine uses water as the working fluid. Water enters the boiler at 60∘C and 3 MPa at a rate of 5.4 kg/s. Water leaves the boiler at 350∘C and at the same inlet pressure and enters the turbine. The water that leaves the turbine enters the condenser at 100∘C and 50 kPa. The water leaves the condenser at 55∘C and 50 kPa.

 

What is the amount of heat absorbed in the boiler?

What is the net work produced by the heat engine cycle?
