| Thermocouples | 8 nos., along the length of the bar |
| Heat Source | Band heater at one end |
| Heat Sink | Water-cooled, at the opposite end |
| Control | Dimmerstat, 0-230V, 2A capacity |
| Measurement | Voltmeter, ammeter, multichannel digital temperature indicator, measuring flask and stop clock |
| Services Required | 230V AC supply with earthing; water supply at 2 lit/min |
Key Features
- Copper bar heated at one end via a band heater, cooled at the other via a water-cooled heat sink
- 8 thermocouples along the bar length map the axial temperature gradient
- Insulated test section minimises radial heat loss for accurate conduction measurement
- Heat conducted through the bar measured by heat collected in the water-cooled sink
- Voltmeter and ammeter measure heater input power
- Measuring flask and stop clock quantify cooling water flow rate
Applications
The Thermal Conductivity Of Metal Rod apparatus is used in heat transfer laboratories to study one-dimensional steady-state conduction, helping students determine the thermal conductivity of a metal rod from measured temperature gradient and heat flow.

Frequently Asked Questions
Q1. What does the Thermal Conductivity Of Metal Rod apparatus measure?
It measures the thermal conductivity of a copper bar based on the temperature gradient and heat conducted from a heated end to a water-cooled end.
Q2. How is temperature measured along the bar?
8 thermocouples fitted along the bar's length feed a multichannel digital temperature indicator.
Q3. How is the conducted heat quantified?
Heat conducted through the bar is measured by the heat collected in the water-cooled heat sink, using a measuring flask and stop clock for water flow.
Q4. Why is the test section insulated?
Insulating the test section minimises radial heat loss, ensuring the measured heat flow represents axial conduction only.
Q5. What utilities are required to operate the apparatus?
It requires a 230V AC supply with earthing connection and a water supply at approximately 2 litres per minute.
