Consider the same tube as the one given in 13.19 but with a constant surface heat flux of 50 kW/m²
and the same inlet conditions.

a. Plot the variation of the mean air temperature along the tube.

 b. Plot the variation of the surface temperature along the tube.

c. Find the mean air temperature and the tube surface temperature at the exit.

 For simplicity, assume fully developed flow and neglect compressibility effects. Assume
