a liquid is flowing over a flat slab consisting of pure solid solute a. as the liquid flows over the surface, solute a dissolves into the liquid. it is desired to maintain laminar flow across the entire surface of the slab, which is 40 cm in length. what is the maximum possible local mass transfer coefficient, kc(x), in this process, and what is the bulk velocity of the liquid? the molecular diffusion coefficient of solute a in liquid b is dab 1.0 10 5 cm2/s, and the kinematic viscosity of the liquid is 0.0020 cm2/s.
