Heat Transfer in Natural Convection

The apparatus consists of a vertical brass pipe heated by a cartridge heater in side it. The Pipe looses heat to atmosphere by natural convection. Pipe 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 by voltmeter and ammeter and can be varied by dimmer stat.


  • Pipe - Brass, 38 mm dia.(OD), 500 mm long fitted with cartridges type heater.
  • Thermocouples fitted along the length of pipe.
  • Enclosure with Perspex window to house the pipe.

Instrumentation & Controls :

  • Digital Voltmeter - 0 - 199.9 Volts.
  • Digital Ammeter - 0 - 1.999 Amp.
  • Multy channel Digital Temperature Indicator.
  • Heater Control.
  • Necessary switches & Fuses.

Service Required :

  • 230 V.A.C. stabilized supply with earthing.
  • Floor space - 1.5 m X 1.5m at working height.
