Mild Steel RLHT-110 Thermal Conductivity Of Metal Rod

The experimental set up consists of 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. A cylindrical shell filled with insulating material surrounds the middle portion of the bar. The temperature of the bar is measured at different sections. Heat Input to the heater is given through variac. By varying the heat input rates, data can be obtained. Water at constant rate is circulated through the jacket and its flow rate and temperature rise is noted. EXPERIMENTATION : To plot the temperature distribution along the length of Bar. To determine the thermal conductivity of given bar at various temperatures. Determination of thermal conductivity of any metal bar other than the supplied one by proper fitting of the bar in the unit.
