Average surface heat transfer coefficient for a pipe losing heat by forced convection to air flowing through it can be obtained for different air flow and heat flow rates.

Renold,s number and Nusselt number for each experimental condition can be calculated. Plot these values on log – log graph. Plot on the same graph the Dittus – Boelter correlation. Compare these two plots.

To plot and comment on the surface temperature distribution along the length of the pipe.
