Quick Answer: Forced Convection Apparatus measures heat transfer from a 32 mm NB GI test pipe, 500 mm long, heated outside by a band heater while a centrifugal blower forces air through it. An orifice meter with differential water manometer measures the airflow, and a multichannel digital indicator reads the temperatures.

About This Product
Constant heat flux is added to the pipe by the electrical heater, and the air forced through it carries the heat away by forced convection. Pipe surface temperatures along its length and air temperatures at inlet and outlet let students calculate local and overall heat transfer coefficients at various airflow rates and heat flux values. In the HEAT TRANSFER LAB, the apparatus needs about 1 m x 0.75 m of bench space at working height.
Frequently Asked Questions
Q1. What can be calculated with the forced convection apparatus? Local and overall heat transfer coefficients in forced convection, at various airflow rates and various heat flux values.
