Derive a differential equation for the temperature in the pin fin as a function of x, the distance from the base. Let To be the base temperature, and write the appropriate boundary conditions for the differential equation. c) Repeat the calculations for the three cases (Part b in Project #1) by using the following parameters: o 5.670374419 x 10-8 W.m-2. K-4 E 0.5 What mechanism of heat transfer is more efficient in this temperature range? What's about the case when the temperature at the base of the fin is To 1000 °C.
