A. Introduction

The primary objective of this experiment to try and understand the heat transfer characteristics from extended surfaces such as cylindrical pins as conduction. Extended surfaces or ‘fins’ as they’re normally referred to, are utilized to increase the rate of heat transfer to or from the environment by increasing convection. Adding fins to an object is often seen as an economical solution to heat transfer issues. We will also study its heat propagation through a combined convection and radiation analysis.

There will be two main parts to this experiment. In the first part, we will study the power lost from a 0.35m brass cylindrical pin due to natural convection and radiation. This will be done by inspecting the input power and the temperature along different points on the pin. The different temperature points will give an idea on the loss of heat between specific sections. The second part will be concerned with studying the combine effect of natural convection/radiation and comparing it with the effects of forced convection/radiation. The latter can be observed by forcing air over the desired interface.

There are certain assumptions that will be made to carry out the said experiment. The heat flow will always be considered one dimensional. The system is considered
