Consider a long bar of square cross section (0.8 m to the side) and of thermal conductivity 2 W/m-K. Three of these sides are maintained at a uniform temperature of 320°C. The fourth side is exposed to a fluid at 100°C for which the convection heat transfer coefficient is 10 W/m2K. Using an appropriate numerical technique with a grid spacing of 0.2 m, determine the midpoint temperature of the bar, in °C, and heat transfer rate between the bar and the fluid per unit length of the bar, in W/m. Tmid= 'com i °C ! W/m
