In dpphat/partFilt: Particle Filtration

Description

Ng_parm Function This function calculates the ratio of the Stokes' settling velocity of the particle to the superficial filtration velocity

Usage

Ng_parm(Kx = 0.02, GRAD = 7e-04, POR = 0.21, K_units = "cm/s",
  TEMP = 25, DIA_SUSP = 1e-04, DIA_SOIL = 0.053, PART_DENS = 2.64)

Arguments

Kx	Defaults to a value of 0.02 cm/s
GRAD	Defaults to a value of 0.0007
POR	Defaults to a value of 0.21. The value of 0.21 is the average for medium sand as reported by Johnson (1967)
K_units	Units of hydraulic conductivity. Defaults to cm/s but also accepts ft/day. Units should be surrounded by quotation marks to ensure it is treated as a string of text.
TEMP	Temperature in units of °C. Defaults to a value of 25°C
DIA_SUSP	Diameter of the suspended solids in units of cm
DIA_SOIL	Diameter of the soil particles in units of cm
PART_DENS	Density of the suspended particle in units of g/cm³
