A small power plant produces 25 kg/s steam at 3 MPa, 600 degrees Celsius in the boiler. It cools the condenser with the ocean water coming in at 12 degrees Celsius and returning at 15 degrees Celsius so the condenser exit is at 45 degrees Celsius. Find the net power output and the required mass flow rate of ocean water.
In a 14 TR ammonia refrigeration plant, the
condensing temperature is 250C and evaporating
temperature -100C. The refrigerant ammonia is
sub-cooled by 5 OC before passing through the
throttle valve. The vapor leaving the evaporator is
0.97 dry. Find: 1. Coefficient of performance: and
2. Power required.
