OT dt Where (a = 0.645 ft/hr) the thermal diffusivity Consider the 2-D heat conduction equation = T(x,0) = T = 200, T(x, h) = T = 0, 0T T dx dy It is required to determine the temperature distribution in a long bar with a rectangular cross-section. T(0, y) = T = 200, T(b, y) = T = 0, + Assume the bar is composed of chrome steel, which has cross sectional dimensions of 3.5 ft by 3.5 ft (b-h-3.5) Initial condition t = 0 T = T = 0.0 Boundary condition t 0
