Thermal Conductivity of Insulating Powder
Product Code : JA-HTLE-7372
The Thermal Conductivity of Insulating Powder apparatus (SKU JA-HTLE-7372) measures how well a powder insulates by making heat flow radially outwards through it. Two thin-walled concentric copper spheres of 100 and 200 mm diameter hold the powder between them, a nichrome coil heats the inner sphere, and ten RTD PT-100 sensors read the sphere surface temperatures. This insulating powder apparatus is used in heat transfer labs at several heat inputs set by a variac.
Specifications
The insulating powder apparatus is specified by an inner sphere of 100 mm and an outer sphere of 200 mm diameter, a nichrome wire heater, ten RTD PT-100 sensors and a control panel with variac, digital voltmeter, ammeter and temperature indicator, as tabled.

Experiments with the insulating powder apparatus
The apparatus is used to determine the thermal conductivity of an insulating powder from the heat input and the temperatures of the two sphere surfaces, and to see how the conductivity changes with temperature.
- Determination of the thermal conductivity of insulating powder
- Comparison of conductivity at different temperatures
- Radial conduction through a spherical shell
- Heat transfer practicals for B.Tech and diploma students
