Thermal Conductivity of Insulating Powder.
Thermal Conductivity of Insulating Powder
Thermal Conductivity of Insulating Powder apparatus consists
of two concentric copper spheres. The insulating powder, (Asbestos) is
filled in the space between the two spheres. An electric heater is
placed at the center of the inner sphere. Four thermocouples are fixed
to the outer surface of inner sphere and eight thermocouples are fixed
to the inner surface of outer sphere. Thermocouples are also used to
measure the temperature of inner and outer surface.The control panel
consists of a dimmers stat to control the voltage supplied to the
heating element. A Voltmeter, an ammeter and a digital temperature
indicator are also provided.
