Thermal Conductivity of Metal Rod
Description:-

Heat Input to the heater is given through variac.
By varying the heat input rates, data can be obtained. 
A cylindrical shell filled with insulating material surrounds the middle portion of the bar. 
The temperature of the bar is measured in different sections. 
The experimental set up consists of a metal bar, one end of which is heated by an electric heater while the other end of the bar projects inside the cooling water jacket. 
Water at a constant rate is circulated through the jacket and its flow rate and temperature rise are noted.

Experimentation:-
To plot the temperature distribution along the length of Bar. 
To determine the thermal conductivity of given bar at various temperatures.
