Air at 30 degree C, 80% RH is cooled by spraying water at 12degreeC. This causes saturation, followed by condensation, the mixing being assumed to take place adiabatically and the condensate being drained off at 16.7 degree C. The resulting saturated mixture is then heated to produce the required conditions of 60% RH at 25 degree C. The total pressure is constant at 101 kPa. Determine the mass of water supplied to the sprays to provide 10 m3/h of conditioned air. What is the heater power required?
