On a cold winter day, the rate of heat transfer from the air in a certain room is 5500 Btu/hr. The room is heated by a heating system, and the warm air is circulated by a fan which develops 0.75 hp. What is the required rate of heat transfer in kW, from the heating system in order to maintain constant room conditions?

A vacuum refrigeration system consists of a large insulated flash chamber kept at low pressure by steam ejector which pumps vapor to a condenser. Condensate is removed by condensate to an air vent. Warm return water enters the flash chamber at 13oC, chilled water comes out of the flash chamber at 5oC Vapor leaving the flash chamber has a quality of 0.97 and the temperature in the condenser is 32oC. For 350 kw of refrigeration How much vapor must the steam ejector remove from the flash chamber?
