Thermal Conductivity Of Insulating Slab.
Thermal Conductivity Of Insulating Slab
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 ofthe specimen. Two
identical specimens are clamped between heater that ensures
unidirectional heat flow through specimen. The whole assembly is kept in
chamber andinsulated by ceramic wool insulation around the set-up.
