Question: Consider the two-dimensional rectangular plate of Problem 4.2 having a thermal conductivity of 50 W/m K. Beginning with the exact solution for the temperature

Consider the two-dimensional rectangular plate of Problem 4.2 having a thermal conductivity of 50 W/m ∙ K. Beginning with the exact solution for the temperature distribution derive an expression for the heat transfer rate per unit thickness from the plate along the lower surface (0 < x < 2, y = 0). Evaluate the heat rate considering the first five nonzero terms of the infinite series.
