please can you solve this step by step and the writing is clear the sbject is mass transfer

If the local Sherwood number for the laminar layer that is formed over a flat plate is Shx=0.332Rex0.5Sc0.33 and for the turbulent layer is Shx=0.0292Rex0.8Sc0.33 evaluate a) The value of the mass-transfer coefficient at a point where the Reynolds number is 70,000 b) The average film-transfer coefficient, kc. for the flat plate from the leading edge to the point where the Reynolds number is 70,000 . c) The value of the mass-transfer coefficient at a point where the Reynolds number is 700,000 Given: - DAB=2.5105sm2 v=1.5105sm2 If the local Sherwood number for the laminar layer that is formed over a flat plate is Shx=0.332Rex0.5Sc0.33 and for the turbulent layer is Shx=0.0292Rex0.8Sc0.33 evaluate a) The value of the mass-transfer coefficient at a point where the Reynolds number is 70,000 b) The average film-transfer coefficient, kc. for the flat plate from the leading edge to the point where the Reynolds number is 70,000 . c) The value of the mass-transfer coefficient at a point where the Reynolds number is 700,000 Given: - DAB=2.5105sm2 v=1.5105sm2
