A vacuum refrigeration system consists of a large insulated flash chamber kept at low pressure by a steam ejector which pumps vapor to a condenser. condensate is removed by a 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 32 c. for 350 kw of refrigeration. a) how much chilled water at 5 deg C does this system provide b) how much make up water is needed c) how much vapor must the system ejector remove from the flash chamber answers: a) 10.41 kg/s b) 0.1521 kg/s c) 21.7 kg/s
