THERMAL CONDUCTIVITY OF METAL ROD APPARATUS

Product Description

The experimental set up consistsof metal bar, one end of which is heated by an electric heater while the otherend of the bar projects inside the cooling water jacket.

A cylindrical shell filled with insulatingmaterial surrounds the middle portion of the bar.

The temperature of the bar ismeasured at different sections.

Heat Input to the heater is Fiventhrough variac.

By varying the heat input rates,data can be obtained.

Water at constant rate iscirculated through the jacket and its flow rate and temperature rise is noted.

Experimentation

To plot the temperaturedistribution along the length of Bar.

To determine the thermalconductivity of given bar at various temperatures.
