THERMAL CONDUCTIVITY OF INSULATING POWDER

/in /by

RANGE OF EXPERIMENTS TO BE CARRIED OUT :
1. To determine the thermal conductivity of the Insulating Material.
2. The experiments can be conducted at various
values of input & calculation can be made accordingly.
3. To plot Heat flux Vs thermal conductivity of Insulating Powder.
TECHNICAL DESCRIPTION :
The apparatus consists of two thin walls concentric copper spheres. The inner sphere houses the heating coil, the insulating powder ( Asbestos Powder, as lagging material ) is packed between two shells. The power supplied to the heating coil is by using a dimmerstat & is measured by Voltmeter & Ammeter.
Copper constant thermocouples are used to measure the temperatures, thermocouples 1 to 4 are embedded on inner sphere and thermocouples 5 to 10 , are embedded on the outer shell
