About This Product
Conduction along a metal bar is a basic experiment in heat transfer courses. With one end heated and the other cooled, the temperature falls along the length of the bar, and the thermal conductivity follows from the heat flow and the temperature gradient. Insulation around the middle section limits side losses, so heat flows mainly along the bar. Students plot the temperature distribution and repeat the test at different heat input rates.
Frequently Asked Questions
Q1. What experiments can be done with this apparatus?
Students can plot the temperature distribution along the length of the bar and determine the thermal conductivity of the bar at various temperatures.
Q2. How is the heat input varied?
The heater is fed through a variac and measured with a digital voltmeter and digital ammeter, so a wide range of heat input rates can be set.
Q3. What utilities are needed?
Water supply of 3 lit/min (approx.) with a drain, a 1 Phase, 220 V AC, 2 Amp electricity supply, and a table for set-up support.
