question

(a) A mixture of air and water vapor is passing over a flat plate 2 ft long at a rate of 210 ft/sec at 1atmand 75°F. Determine the mass transfer coefficient of water vapor in air if the flow is turbulent and the concentration of water vapor in air is very low (i.e.,P_bm/ P \approx 1). (b) Find the mass transfer coefficient of water vapor in air when the mixture is passing over a sphere 3 in.indiameter. Assume all other conditions to be same as in part (a).
