Settling Velocity Functions
Stokes and hindered settling of proppant in fracturing fluid.
3 functions
PO.FRAC.Proppant.Vs.Stokes(dp, Rho_p, Rho_f, Ul)
Stokes settling velocity (infinite dilution), [ft/min].
PO.FRAC.Proppant.Vs.StokesField(dp, SG_p, SG_f, Ul)
Stokes settling velocity using specific gravity (field units), [ft/min].
PO.FRAC.Proppant.Vs.Hindered(vs, Cv)
Hindered settling velocity (Richardson-Zaki), [ft/min].
