PART I. Analytical solution

A fin of unusual shape protrudes from a surface whose temperature is 200 o C. The first section of the fin is rectangular and the second part is triangular as shown in the figure below. The length of the rectangular section is 12.5 cm and the length of the triangular section is 10 cm. The width of the fin is 100 cm (into the page) and the thickness of the rectangular section is 1 cm. The fin material has a thermal conductivity of 100 W/m-K and the surrounding air is at a temperature of Tinf = 30 o C and a convective heat transfer coefficient of 30 W/m2 -K.

PART I. Analytical solution

(a) Determine the temperature at the location where the fin changes from rectangular to triangular shape.

(b) What is the heat transfer rate from the fin to the fluid?
