A 15-cm x 20-cm circuit board is being cooled by forced convection of air at 1 atm. The heat from the circuit board is estimated to be 1000W/m^2. If the air stream velocity is 3 m/s andthe shear stress of the circuit board surface is0.075 N/m^2, determine the temperature difference between the circuit board surface temperature and the air stream temperature.Evaluate the fluid properties at 40 deg-C.
