a. Outside air, initially at 55oF db and 40oF wb, at the rate of 500 cfm is heated and humidified to 85oF and 60% relative humidity. Calculate (a) the heat transfer rate and (b) the amount of moisture added to the air stream. Answers: a. _______heat transfer rate Btu/min b. _______moisture added lb/min
a. Outside air, initially at 55oF db and 40oF wb, at the rate of 500 cfm is heated and humidified to 85oF and 60% relative humidity. Calculate (a) the heat transfer rate and (b) the amount of moisture added to the air stream.
Answers: a. _______heat transfer rate Btu/min
b. _______moisture added lb/min
b. Moist outside air at 100oF db and 75oF wb is cooled to 70oF db and 50% relative humidity. The volume flow of air is 2500 cfm, and the condensate leaves at 72oF. Calculate (a) the heat transfer rate and (b) the amount of moisture removed.
Answers: a. _________heat transfer rate Btu/min (10 points)
b._________ moisture removed lb/min
