8. Emissivity of a Test Surface l Radiation Heat Transfer Experiment

This video is about,
Trial on Emissivity measurement Setup to experimentally determine Emissivity of a given test surface. The emissivity of any surface other than perfectly black body is always less than 1. This trial will help students to understand the relation of emissive power of real surface to that of a black body.
Also at the end effect of temperature on emissivity is discussed.

For any subject related questions, feel free to comment, it will surely be answered.

The trial is conducted at Heat Transfer Lab of Sanghavi College of Engineering, Nashik where, the speaker is working as Heat of Department at department of mechanical engineering.
