question

Consider an air stream flowing over a smooth solid naphthalene plate with a velocity of 116 ft/sec at points far away from the surface of the plate. The air stream pressure is 1 atm. and the temperature of the system is 115°F. Assume the influence of non-unity Schmidt number is negligible. Assuming turbulent boundary layer from the leading edge, determine the following: (a) the average coefficient of mass transfer over the first 1.5 ft from the leading edge of the plate. (b) the average mass transfer rate per unit width over the first 1.5 ft from the leading edge of the plate. (c) the local coefficient of mass transfer at 1.5 ft from the leading edge of the plate. (d) the local concentration gradient of naphthalene at the surface at 1.5 ft from the leading edge.
