THERMAL CONDUCTIVITY OF INSULATING POWERED APPARATUS

Product Description

Description

Insulating Powder apparatus is designed to determine thethermal conductivity of insulating Powder. The Apparatus consists of twothin-walled concentric copper spheres. Inner sphere houses Nichrome Wireheating coil. Insulating Powder is fitted between the spheres. Heat flowsradically outwards.

Temperature sensors at proper positions are fitted tomeasure surface temperatures of spheres. Heat input for the heater is giventhrough a Variac and measured by Digital Voltmeter & Digital Ammeter. Byvarying the heat input rates, wide range of experiments can be performed.

Experiments

Determination of thermal conductivity of insulating powder.

Comparison of thermal Conductivity of insulating powder atdifferent temperatures.
