Description Usage Arguments Examples
eta_parm Function This function calculates the single particle/collector removal efficiency [Equation 6 from Tobiason and O'Melia (1988)]
1 2 | eta_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)
|
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 |
