Thermal Conductivity Of Insulating Powder

Thermal Conductivity Of Insulating Powder

• This apparatus is designed to determine the thermal conductivity of insulating powder. The apparatus consists of two thin walled concentric copper spheres. Inner sphere houses Nichrome Wire heater
• Insulating powder is filled between the two spheres
• Heat flows radially outwards. Temperature sensors at proper positions are fitted to measure surface temperatures of spheres
• Heat input to the heater is given through a variac and measured by Digital Voltmeter & Digital Ammeter. By varying the heat input rates, data can be obtained

Experiment:

• Determination of thermal conductivity of insulating powder
• Comparison of thermal Conductivity of insulating powder at different temperatures

Utilities Required:

• Electricity Supply: 1Phase, 220 V AC, 2 Amp.
• Table for set-up support
