In an uncomfortable summer day, the air is at 87OF and 80% relative humidity.

If the vent switch on the air conditioner is turned to the open position, outside air enters the unit as shown belown the air conditioner, the air is cooled to a temperature low enough to condense the necessary amount of water and reheated to 55OF, at which point it has the same absolute humidity as the room air. Determine the rate (lb/min) at which water is condensed, the temperature to which the air must be cooled to condense water at this rate, and the net tons of cooling required (Q), where 1 ton of cooling = -12,000 Btu/h.

Question
In an uncomfortable summer day, the air is at 87OF and 80% relative humidity. A laboratory air conditioner is to deliver 1.00 x 103
ft3/min of air at 55OF in order to maintain the interior air at an average temperature of 75OF and relative humidity of 40%.
a. If the vent switch on the air conditioner is turned to the open position, outside air enters the unit as shown belown the air conditioner, the air is cooled to a temperature low enough to condense the necessary amount of water and reheated to 55OF, at which point it has the same absolute humidity as the room air. Determine the rate (lb/min) at which water is condensed, the temperature to which the air must be cooled to condense water at this rate, and the net tons of cooling required (Q), where 1 ton of cooling = -12,000 Btu/h.
Assume A = 87 οF, B = 80 %, C = 55 οF.
