This painted surface is exposed to ambient air at 27°C flowing at 20 km/hr, while the bottom side of the surface is exposed to a constant heat source from a heating band providing 150 W/m2. Assume the plate to be infnitely thin (we neglect the thickness) and that all air properties (including at film temperature) can be approximated as air properties at 300K. b) Calculate the average convection coefficient of the plate side exposed to the air flow c) Using first law, show the equation that needs to be solved to calculate the painted surface temperature. DO NOT SOLVE THE EQUATION.
