Consider the plate conveyor system of Problem 7.24, but now under conditions for which the plates are being transported from a liquid bath used for surface cleaning. The initial plate temperature is T_i = 40°C and the surfaces are covered with a thin liquid film. If the air velocity and temperature are u_∞ = 1 m/s and T_∞ = 20°C, respectively, what is the initial rate of heat transfer from the plate? What is the corresponding rate of change of the plate temperature? The latent heat of vaporization of the solvent, the diffusion coefficient associated with transport of its vapor in air, and its saturated vapor density at 40°C are h_fg = 900 kJ/kg, DAB = 10^-5 m²/s, and P_A,sat = 0.75 kg/m 3 , respectively. The velocity of the conveyor can be neglected relative to that of the air.
