The Creative Labs unit consist 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 measurement at various points along length of pipe. Temperature of air at inlet and outlet of test section are measured. Thus the students can calculate local and overall heat transfer coefficients in forced convection, at various airflow rates and various heat flux values.
