A rectangular intake air duct is 36 in. wide and 24 in. high. It runs for over 300 ft inside a warehouse and is at 50 F, but one end of the duct opens to the outside where outside air can enter the duct. If 120 cfm ( cubic feet per minute ) of outside air at 12 F enters the duct, estimate the air temperature 200 ft inside the duct.
