EMISSIVITY - NATURAL CONVECTION AND RADIATION

Trolley mounted, mobile apparatus that demonstrates how different types of heat can transfer over a range of pressures; helps the understanding of the Stefan Boltzmann constant.

The Natural Convection and Radiation equipment allows the study of heat transfer at different pressures and vacuum. It shows the differences between radiation and natural 'free' convection. It allows students to find the emissivity of a surface and verify the Stefan-Boltzmann equation.

Attached to its surface is a thermocouple to measure the temperature. Learn about EMISSIVITY - NATURAL CONVECTION AND RADIATION for educational labs for optimal educational outcomes.. The vessel's inside is also black, and it has a thermocouple fitted to its wall to measure the temperature in the vessel. The vessel may be charged with compressed air up to 1 bar (gauge) or evacuated down to about 5 Pa (absolute).

This allows them to isolate the heat transfer by radiation. Learn about EMISSIVITY - NATURAL CONVECTION AND RADIATION price for optimal educational outcomes..
