Question

This question Has multiple parts, i need just the Part B solved, Part A is about driving the equation that is mentioned in part a, Use that equation and the table to solve part b, should be simple.

1a. Consider the problem 2-15 from Ozisik (1993). Starting with the heat diffusion equation, Eq. 1-11a in Ozisik (1993), show how it can be reduced to: a²T ²T + = 0 əx² əy² in [0<x<a; 0<y<b], subjected to the following boundary conditions: ƏT ƏT = 0 at x = 0; +HT = 0 at x = a; ax əx T = f(x) at y = 0; ƏT + HT = 0 at y = b ду All assumptions must be clearly stated and justified, and all steps clearly explained. 1b. Using separation of variables, show how the eigenfunction from Table 2-2 in Ozisik (1993) was derived. X(Pm, x) = cospmx Each step of your formulation must be clearly explained, and all assumptions justified.
