4. The boundary layer solution for a plate predicts the following equations: for laminar flow: Sh, = 0.332 Re,'2,13 415 for turbulent flow: Sh, = 0.0292 Res. evaluate; (a) The value of the mass-transfer coefficient at a point where the Reynolds number is 70,000. (6%) (b) The average film-transfer coefficient, ke, for the flat plate from the leading edge to the point where the Reynolds number is 70,000. (8%) (C) The value of the mass-transfer coefficient at a point where the Reynolds number is 700,000. (6%) (Hint: Show the convective mass-transfer coefficient as a function of Se and ve, where is the velocity of the solution.)
