THERMAL CONDUCTIVITY OF METAL ROD APPARATUS

Product Description

Specification:

THERMAL CONDUCTIVITY OF METAL ROD APPARATUS

The experimental set up consists ofmetal bar, one end of which is heated by an electric heater while the other endof the bar projects inside the cooling water jacket.

A cylindrical shell filled withinsulating material 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, datacan be obtained.

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

Experimentation

To plot the temperature distributionalong the length of Bar.

To determine the thermal conductivityof given bar at various temperatures.

Utilities Required
