2. 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 13°C, chilled water comes out of the flash chamber at 5°C Vapor leaving the flash chamber has a quality of 0.97 and the temperature in the condenser is 320C. For 350 kw of refrigeration (a) How much chilled water at 5°C does this system provide? (b) How much make-up water is needed? (c) How much vapor must the steam ejector remove from the flash chamber?
1) Water vapor with a flow rate of 20000 kg / h enters the condenser of a power plant at a pressure of 20 kPa and a dryness degree of 95 percent. In the condenser, there is heat transfer to the river water flowing through the pipes. The temperature rise of the river water is limited to 10'C to prevent thermal pollution. Since the state of the water at the condenser outlet is saturated liquid at 20 kPa pressure, what should be the flow rate of the cooling water.
