HEAT TRANSFER IN FORCED CONVECTION

RANGE OF EXPERIMENTS TO BE CARRIED OUT:

1. 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 & heat flow rates.
2. Reynold’s number & Nusselt number for each experimental condition. To Plot these values on Log – log graph. To Plot on the same graph the Dittus-Boelter correlation.
3. To plot & comment on the surface temperature distribution along the length of pipe.

EXPERIMENTAL SETUP :

1. Band Heater Assembly.
2. Forced convection pipe assembly.
