Question

5.0 Air at p=p= 1 atm enters a thin-walled (D=D= 5-mm diameter) long tube (L=L= 2 m) at an inlet temperature of Tm,i=Tm,i= 100°C. A constant heat flux is applied to the air from the tube surface. The air mass flow rate is m˙ =m˙⁢ = 125 × 10-6 kg/s. If the tube surface temperature at the exit is Ts,o=Ts,o= 160°C, determine the heat rate entering the tube, in W. Evaluate properties at T=T=400 K.
