Natural Convection Apparatus — specification
The Natural Convection Apparatus is built at our works in Ambala Cantt and supplied to vocational training laboratories worldwide, as a single unit or in quantity against a tender schedule. It is listed with the rest of our Technical And Vocational Education Lab.
The unit consists of a vertical brass pipe heated by a cartridge heater
inside it. The pipe looses heat to atmosphere by natural convection. It
is fitted in an enclosure to provide undisturbed natural convection
currents. Thermocouples are attached on the pipe to measure local
temperatures. Heater input is measured on voltmeter and ammeter. Thus
students can determine overall heat transfer coefficient and local
transfer coefficients in natural convection at various heat transfer
rates.
