SEARLE’S THERMAL CONDUCTIVITY APP

SEARLE’S THERMAL CONDUCTIVITY APPARATUS – Physics Equipment

Searle’s thermal conductivity apparatus: it consist of a copper rod 30 x 2. 5 cms dia with its one end surrounded with a steam jacket for heating it from a boiler and the other end is kept cool by a steam of water flowing throughout a spiral tube fitted on that end fitted in a well polished teak wood case w/o thermometer and boiler.

• This apparatus is used to find the thermal conductivity of good conductors.
• Its importance in the field of thermodynamics that cannot be understated
• The apparatus consists of a cylindrical Copper pipe.
• One end of the rod is surrounded by a steam jacket, for heating the rod using a boiler, and the other end is kept cool using a spiral tube through which a constant stream of water is made to flow.
• The Copper pipe has tubes for inserting thermometers.
• The apparatus is fitted in wooden case lined with felt for thermal insulation.
• The front portion of the case is hinged which can be opened for demonstration. Supplied without thermometers and steam boiler.
