N air conditioner is designed to bring 10,000 ft3/min of outside air (90°F, 29.8 inches Hg, 88% relative humidity) to 40°F, thereby condensing a portion of the water vapor, and then to reheat the air before releasing it into a room at 65°F. Calculate the rate of condensation (gallons H2O/min) and the volumetric flow rate of the air delivered to the room. (Suggestion: On the flowchart, treat the cooling–condensation and the reheating as separate process steps.)
