Heat Transfer In Natural Convection  Name
 
(Code - ALABS-A143-027 ) | Altec Export Lab Specification:
Heat Transfer In Natural Convection : Heat Transfer In Natural Convection 
  • The setup consists of a brass tube fitted in a rectangular duct in a vertical position.
  • The duct is open at the top and bottom, and forms an enclosure that serves the purpose of undisturbed surrounding.
  • One side of the duct is fitted with a transparent acrylic window for visualization.
  • An electric heating element is kept in the vertical tube that in turns heats the tube surface.
  • The heat is lost from the tube to the surrounding air by natural convection.
  • The temperature of the vertical tube is measure by temperature sensors and displayed by a Digital Temperature Indicator with multi channel switch.
  • The heat input to the heater is measured by a Digital Ammeter and a Digital Voltmeter and is varied by a variac. The tube surface is polished to minimize the radiation losses.
Experimentation:
  • To determine average heat transfer coefficient under natural convection
Utilities required:
  • Electricity Supply : 1 Phase, 220 V AC, 2 Amp.
  • Table for set-up support
