kinvisc: Calculate the kinematic viscosity of a fluid.

Description Usage Arguments Value Author(s) See Also Examples

The kinematic viscosity of a homogeneous body or fluid is defined as the value of its dynamic viscosity divided by its density. This function can also divide by gravity, which would be necessary in the computation of, for example, hydraulic conductivity.

1 2	kinvisc(dyn_visc = NULL, fluid_dens = NULL, grav.divide = FALSE, verbose = FALSE)

`dyn_visc`	scalar; representing the dynamic fluid viscosity, with units [Pa \cdot s]
`fluid_dens`	scalar; representing the fluid density, with units [kg m^{-3}]
`grav.divide`	logical; should the kinematic viscosiy be divided by standard gravitational acceleration?
`verbose`	logical; should messages be displayed?

scalar, a form of kinematic viscosity with units or either:

[m^2 s^{-1}] if grav.divide==FALSE
[m s] if grav.divide==TRUE
