Question: A thin plate of solid salt, NaC1, measuring 15 by 15 cm, is to be dragged through seawater at a velocity of 0.6 d s

A thin plate of solid salt, NaC1, measuring 15 by 15 cm, is to be dragged through seawater at a velocity of 0.6 d s . The 291 K seawater has a salt concentration of 0.0309 g/cm3 and a density of 1.022 g/cm3. Estimate the rate at which the salt goes into solution if the edge effects can be ignored. Assume that the kinematic viscosity at the average liquid film conditions is 1.02 x lod m2/s, and the diffusivity is 1.25 x m2/s.The solubility of NaCl in water at 291 K is 0.35 g/cm3, and the density of the saturated solution is 1.22 g/cm3. The correct answer is 0.86 kg/h. How?
