Thermal Conductivity of Insulating Powd
er

DESCRIPTION

Insulating Powder 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 heating coil. Insulating Powder is fitted between the spheres. Heat flows radically outwards. Temperature sensors at proper positions are fitted to measure surface temperatures of spheres. Heat input for the heater is given through a Variac and measured by Digital Voltmeter & Digital Ammeter. By varying 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 at different temperatures.

TECHNICAL DETAILS

  • Inner Sphere : 100 mm dia.Outer Sphere : 200 mm dia.Heater : Nichrome WireTemperature Sensors : RTD PT-100 Type (10 Nos.)Control Panel : Digital Voltmeter: 0-300 Volt.Digital Ammeter: 0-2 Amp.Variac : 0-230 V / 2 Amps.Digital Temperature Indicator: 0-300oCWith Multi-Channel Switch, ON/OFF Switch, Mains Indicator.
