Radial Heat Conduction

Description

Specification:

• Small-scale accessory to introduce students to the principles of radial heat conduction, and to allow the conductivity of a solid brass disk to be measured.
• Comprises a brass disk with a heater at the centre and a cooling water tube attached to the periphery.
• Six thermocouples measure the temperature gradient between the heated centre and the cooled periphery of the disk.
• Thermally insulated to minimise errors due to heat loss.
• Includes a water pressure regulator and a manually operated valve to control the flow rate.
• Includes an electronic proportioning solenoid valve to control the cooling water flow rate, a pressure regulator and a water flowmeter.
• Heater power variable up to 100 Watts.
• Water flow rate variable up to 1.5 litres/ minute.
• Conduction disk is 110mm diameter and 3.2mm thick.
