Thermal Conductivity of Metal Rod Apparatus.
Thermal Conductivity of Metal Rod Apparatus
Metal Rod Apparatus consists of a metal rod horizontally
placed in a M.S. cylinder (insulating jacket) & is insulated by
covering the metal rod by insulating powder. An electric heater is fixed
at one end of rod while the other end protrudes in to a water jacket.
The heat flows through the rod by mode of conduction. A number of
thermocouples are fixed along the length of rod.Six thermocouples are
embedded along the length of the rod to measure the temperature
distribution. Four more thermocouples are placed within the insulating
powder while two thermocouples measure the water temperature at inlet
& outlet. 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.
