A 10-cm long and 20-cm wide circuit board is covered with 100 closely spaced chips, each generating heat at a rate of 0.08 W and transferring it by convection to the surrounding air at 25°C. Heat transfer from the back surface of the board is negligible. What is the average surface temperature of the chips? The convective heat transfer coefficient on the surface of the board is 10 W/(m^2 K) and radiative heat transfer is negligible. Show all steps and work.
