A long bar of rectangular cross section, 0.4 m x 0.6 m on a side and having a thermal conductivity of 1.5 W/m x K, is subjected to the boundary conditions shown below. Two of the sides are maintained at a uniform temperature of 200 C. One of the sides is adiabatic, and the remaining side is subjected to a convection process with ambient temperature (T-amb) =30 C and h = 50 W/m^2 x K. Using an appropriate numerical technique with a grid spacing of 0.1 m, determine the temperature distribution in the bar and the heat transfer rate between the bar and the fluid per unit length of the bar.
