Thermal Conductivity of Insulating Slab Apparatus

Product Description

Thermal Conductivity of Insulating Slab Apparatus:-

The set-up is designed to determine thermal conductivity of insulating materials in the form of slab. The apparatus consists of main central heater and ring guard heater, sandwiched between the specimens. Cooling plates are provided on either side of the specimen. Two identical specimens are clamped between heater that ensures unidirectional heat flow through specimen. The whole assembly is kept in chamber and insulated by ceramic wool insulation around the set-up.

Experimentation:

•     Determination of thermal conductivity of insulating material in the form of slab.
•     Study of variation of thermal conductivity of the material with temperature.
