Problem
Answer published by the source. Consult the official source to check your work against its answer.
question
Air flows through a tube, and heat is transferred by means of forced convection. The tube is 1 ft. long, with an internal diameter of 2 in. The wall surface temperature is constant at 80°F, and the pressure drop over the length is 0.02 in. of water. The air flow velocity is 20 ft/sec, and the entrance temperature is 300°F. Calculate the exit temperature, given the density of air to be 0.08lbm/ft^3.
