2. Estimate the value of mass transfer coefficients, kc and kG, in large of stream of air at 273K flowing in a duct past the flat plate of solid naphthalene with length of 40 cm. The velocity of the air is 0.82 m/s at 273K and 1 atm abs. The diffusion coefficient of naphthalene in air at 273K and 1 atm abs is 5.16x10-6 m2 /s
