Heat Conduction In Gases and Liquids

Product Description

Heat Conduction in Gases and LiquidsTechnical Description of Heat Conduction in Gases and LiquidsThis 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.Specification of Heat Conduction in Gases and Liquids Study of the heat conduction of gases and liquids Experiments in annular gap formed by 2 concentric cylinders Experimental media water, oil, air Radiation portion of heat transfer negligible due to low temperatures and polished surfaces Adjustable electric heater Manual valves for flow rate adjustment (cooling water, medium to be investigated) Measuring amplifier with digital displays for temperature difference and heater power and control elements Technical Data of Heat Conduction in Gases and LiquidsHeat exchanger Effective heat transfer area: 0,15m Mean effective diameter: 39,6mm Gap width: 0,4mm Heater Max.
