Chapter 32, Problem 4P

Compute the steady-state distribution of concentration for the tank shown in Fig. P32.4. The PDE governing this system is

$D\left(\frac{{\partial }^{2}c}{\partial x^2}+\frac{{\partial }^{2}c}{\partial y^2}\right)-kc=0$

and the boundary conditions are as shown. Employ a value of 0.5 for D and 0.1 for k.
