Athin film of material containing species a at a concentration of 10 mm is placed on the surface of a solid sphere with radius 2 mm. water at 25c flows past the sphere with an average velocity of 1.0 cm/s. the diffusion coefficient of species a in water is 1.0 × 10-10 m2/s. the partition coefficientfor species a in the solid relative to the fluid is 2.0. find the mass transfer coefficient for species a in water and find the flux of a from the sphere surface if the concentration of a far from the surface is zero.
