2. What are Fins ?
Fins are extended surfaces used to increase the rate of heat transfer.
It is made of highly conductive materials such as aluminum.

3. Analysis of Fins Steady state operations No heat generation
Constant thermal conductivity
Constant and uniform convection heat transfer coefficient

4. Fin Equation

7. Boundary conditions

10. Under steady conditions, heat transfer from the exposed surfaces of the fin is equal to heat conduction to the fin at the base.

25. Assumptions The base Temperature = the water temperature
The temperature varies in the axial direction only
Negligible heat transfer from the tip (insulated)
Constant heat transfer coefficient
