Calculate the value of mass transfer coefficient and the flux for mass transfer from a sphere of naphthalene to air at 45C and 1 atm abs flowing at a velocity of 0.305 m/s. The diameter of the sphere is 25.4 mm. The diffusivity of naphthalene in air at 45C id 6.92*10^-6 m^2/s.and the vapor prssure of solid naphthalene is 0.555 mmHg.
