Forced Convection Inside Tube Apparatus
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. The unit consists of a circular pipe, loosing heat by forced convection to air, being forced through it. Constant heat flux is added to pipe by an electrical heater, provided with input control. The pipe surface temperature is measured at various points along length of pipe using thermocouples. Temperature of air at inlet and outlet of test section is measured using temperature indicator.
