Question
A cooling tower is used to reject 1,000,000 Btu/hr from the condenser of a refrigeration system. Determine the water and air flow rates necessary to maintain a condenser leaving temperature of 100 F as the ambient temperature varies between 60 and 100 F at a relative humidity of 50 %. The tower approach is 10 F and the air outlet state is 90 F and saturated. Draw some conclusions from your analysis. (tower approach is the temperature difference between (outlet water temp. - Dew point of intlet air)).Explanation / Answer
Theanswer of following question is as follows.
The water flow rate is 78m3/sec .
While the air flow rate is 56 m3/sec.
