Airflow through a long, 0.1-m-square air conditioning duct maintains the outer duct surface temperature at 15°C. If the horizontal duct is uninsulated and exposed to air at 35°C in the crawlspace beneath a home, what is the heat gain per unit length of the duct? Evaluate the properties of air at Tr =300 K. For the sides of the duct, use the more accurate Churchill and Chu correlations for laminar flow on vertical plates.
