Sedimentation rate of particles

If the particles are larger than the density of seawater, they will sediment gravitationally. Calculate the sedimentation rate.
-
When particles move in water, a resistive force acts on them. Stokes' theorem is used to calculate that resistive force, which is Stokes sedimentation.
-
Assuming the density of the particles, we calculated the sedimentation rate of particles of a given size according to Stokes' equation.
-
The formula for Stokes sedimentation is now available in an Excel sheet. Entering seawater, particle density, and temperature (viscosity coefficient depends on temperature), the sedimentation rate for each particle size can be calculated. It can also be output as a double-logarithmic graph. The yellow cells indicate where to enter the values in Excel and the orange cells indicate where to output them.
