    Seperation of variables - Product solutions for unsteady heat conduction

    Hey guys, I was wondering about problem 12C.1 in Transport phenomena by Bird, Stewart and lightfoot. The problem states that a block of material initially at uniform T0 is suddenely exposed to T1 at all surfaces. Assume a solution of T=X(x,t)Y(y,t)Z(z,t) any help with...
