THERMAL CONDUCTIVITY OF METAL ROD
| The apparatus consists of a solid brass rod of 31.7 mm diameter and length 300.0
mm. One end of the rod is fitted with a copper flange of diameter 82.0 mm and
thickness 5.0 mm.
An electric heater is attached to this end of rod. The other end opens to a cooling
water chamber through which cooling water at a controlled rate is passed.
Four thermocouples (No.1 to 4) are also inserted up to the central line of the solid
brass rod to measure the axial temperature.
Two thermocouples are also pasted over the insulated portion to measure its airside
surface temperature for computation of the heat loss to air.
| To determine the thermal conductivity of a metal rod using one dimensional heat
To plot the temperature distribution along the length of the metal rod.
| Electrical Supply (Single phase, 15 Amp)
Water supply to fill tank.
