Heat Transfer In Forced Convection Manufacturer,Supplier and Exporter in India
Product Code : EL-HTIFC-7375
Jlab Export is a leading Heat Transfer In Forced Convection Manufacturer,and suppliers in India
Heat Transfer In Forced Convection (code EL-HTIFC-7375) is a lab set-up for measuring the convective heat transfer coefficient inside a heated pipe while a blower drives air through it. The test pipe is connected to the delivery side of the blower together with an orifice that measures the air flow, and a nichrome wire heater surrounding the test section supplies a constant heat flux. This blower-and-pipe rig is made by JLab in Ambala, India.

Calculating h From One Set of Readings
Once the temperatures are steady, the heat input is Q = V × I from the digital voltmeter and ammeter. The four surface sensors are averaged to give the pipe surface temperature Ts, and the inlet and outlet air sensors give the mean air temperature Ta = (Tin + Tout)/2. With the heated surface area of the test section A = πdL, the average heat transfer coefficient is h = Q / [A (Ts − Ta)]. Because the orifice reading is taken at the same time, each value of h belongs to a known air flow rate.
Varying the Air Flow and the Heat Input
Two of the experiments compare h at different air flow rates and at different heat inputs. A higher air flow raises h, so the pipe runs cooler for the same Q, while the variac changes the heat flux at a fixed flow. Plotting the four surface temperatures against their position gives the surface temperature distribution along the pipe, which climbs towards the outlet as the air warms up.
Other Convection Set-ups
- Heat Transfer In Natural Convection — measures h for a heated vertical brass tube without a blower.
- Forced Convection Apparatus — copper test pipe version with an orifice plate and U-tube manometer.
- Heat Transfer From Pin-Fin Apparatus — tests a pin fin in a blower-fed duct, with the blower off or on.
