A thin flat plate 6in square with a surface temperature maintained at 250°F is tested for drag in a wind tunnel with an airspeed of 100ft/s. The air is at standard sea level pressure and 60°F and flows over the top and the bottom of the plate. This flow results in a total drag force of 0.0135lbf. Considering the definition of the friction coefficient and Reynolds analogy (eqn 4.40), calculate the rate of heat transfer from this plate.
