A printed circuit board dissipates 100 W from one side over area 0.3 m by 0.2 m. A fan is used to cool this board with a flow speed of 12 m/s parallel to the longest dimension of the board. Using the average Nusselt number relationship, calculate the surface temperature of the board for an air temperature of 30 ℃
