A thin-walled, uninsulated 0.4 m diameter duct is used to route chilled air at 0.07 kg/s through the attic of a large commercial building. The attic air is at 37oC, and natural circulation provides a convection coefficient of 4 W/m2K at the outer surface of the duct. If chilled air enters a 16 m long duct at 7oC, what is its exit temperature and the rate of heat gain? Properties of the chilled air may be evaluated at an assumed average temperature of 300 K.
