Advanced Separation process

On a warm summer's day, a forced-draft cooling tower was found to cool water from 45C to 32C by counter-current contact with air at 34C(23C wet-bulb temperature ). The outlet air was found to be at 24C(22C wet-bulb temperature ). The water flow-rate was 4,000 kg/m2h Under normal conditions, the air would be expected to be at 20C (wet-bulb temperature 17C ). Estimate the extent to which 4,000kg/m2.h of water at 45C may be expected to be cooled under these conditions
