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?
