Description Usage Arguments Value Examples
settle
calculates the settling velocity for a particle, given some parameters.
1 |
ws_mode |
Denotes whether to use a 'simple' equation, neglecting the shape and roundness of particles, or to use the more 'complex' formulation |
D |
The grain size you wish to calculate settling velocity for. |
constants |
A list of constants for calculation, need in order (g) gravitational constant, (rhos) sediment density, (rhof) fluid density, (nuu) kinematic viscosity, (csf) corey shape factor, and (PI) Powers roundness index. For the simple formulation, neglect the last two. Defaults to constants = list(g = 9.8, rhos = 2650, rhof = 1000, nuu = 1.004e-6, csf = 0.7, PI = 3.5) |
Returns a list with two values $ws
and $wstar
which are the settling velocity and dimensionless settling velocity, respectively.
