Air at p = 1atm enters a thin-walled (D = 5-mm diameter) long tube (L = 2 m) at an inlet temperature of Tmi = 100°C. A constant heat flux is applied to the air from the tube surface. The air mass flow rate is m = 140 × 106 kg/s. If the tube surface temperature at the exit is T,, = 160°C, determine the heat rate entering the tube, in W. Evaluate properties at T = 400 K. q = i w
