Sketch the mixed mean and surface temperature profiles for the duct flow depicted below which is subjected to a sinusoidal surface heat flux along its length. Assume that the amplitude of the sinusoidal surface heat flux input is much smaller than its average value so that constant surface heat flux conditions can be assumed for the treatment of the
