Heat Conduction In Gases and Liquids

Product Description

Heat Conduction in Gases and Liquids

Technical Description of Heat Conduction in Gases and Liquids

This experimental unit enables experiments to be performed on steady-state thermal conduction in liquid and gaseous materials. It comprises a cylindrical heat exchanger with a heated inner cylinder made of aluminium and a water-cooled jacket. The medium for the experiment is fed through a gap. The gap between the two elements was selected so that the transfer of heat due to convection can be ignored. Due to the low temperatures and the polished surfaces, the radiation portion of the heat transfer is also negligible. Temperature sensors measure the temperature difference.
