Thermal Conductivity of Metal Rod
Product Code : LSK-TWL-10814
Thermal Conductivity of Metal Rod (SKU LSK-TWL-10814) is a heat transfer bench in which a metal bar is heated at one end and cooled by a water jacket at the other, so students can measure how heat is conducted along it. It serves mechanical and chemical engineering heat transfer laboratories and diploma courses. Science Lab Supplies manufactures the set-up at its Saha, Ambala factory (Plot 448, HSIIDC Industrial Area) and supplies it directly to colleges, tender contractors and distributors.
Specifications
Every technical detail of the set-up is listed in the table below. In short, a metal bar is heated at one end by an electric heater fed through a variac, its other end projects into a cooling water jacket, and an insulated cylindrical shell surrounds the middle portion where temperatures are read at several sections.

Applications and Experiments for the Thermal Conductivity of Metal Rod
The apparatus is used to find the thermal conductivity of the bar at different temperatures and to plot the temperature distribution along its length. Heat carried away by the jacket water, found from its flow rate and temperature rise, gives the heat conducted through the insulated section.
- B.Tech/B.E. mechanical engineering heat transfer lab: conduction through a metal bar.
- Chemical engineering heat transfer practicals: steady-state conduction and energy balance, with jacket water temperatures read on a Glass Thermometer.
- Polytechnic diploma courses: temperature profile along a heated rod, timing the jacket water flow with a Digital Stopwatch.
- Repeating the test at several heat inputs to see how conductivity changes with temperature; a Constant Level Tank keeps the water flow uniform despite supply pressure changes.
Standard Scope of Supply
The set-up is supplied as one bench unit: the metal bar with its electric heater and variac, the cooling water jacket, the insulated cylindrical shell and the temperature measuring points along the bar. A water supply for the jacket is arranged in the laboratory; any optional items are listed on the quotation.

Frequently Asked Questions
What does the thermal conductivity experiment measure?
It measures the thermal conductivity of the metal bar at different temperatures and gives the temperature distribution along the bar, using the heat picked up by the cooling water as the conducted heat.
How is the heat input changed?
The heater is fed through a variac, so the input can be set to different levels. Readings are taken at each setting once temperatures along the bar become steady.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The apparatus is made in its own factory in Saha, Ambala, India, and quotations come directly from the factory.
Can it be quoted as part of an engineering lab tender?
Yes. Send the tender item list, quantities and delivery location through the contact page to receive an item-wise quotation from Science Lab Supplies for engineering lab equipment in India or abroad.
