Question:

Air enters an evaporative cooler at 1 atm, 38oC and 15% relative humidity at a rate of 5 m3/min, and it leaves with a relative humidity of 80%. Determine
(a) The exit temperature (T2) of the air,
(b) The required rate of water supply to the evaporative cooler.
(c) What-if Scenario: What would the required rate of water supply be if the moist air entered the evaporative cooler at a rate of 10 m3/min instead of 5 m3/min?
