R Documentation
Returns Schmidt number for a specific gas at a given temperature
Description
Schmidt number is temperature dependant, and is the ratio of the kinematic viscosity of water
to a diffusion coefficient. Coefficients are included for He, O2, CO2, CH4, SF6, N2O, Ar, and N2.
Usage
getSchmidt(temperature, gas)
Arguments
temperature
Numeric vector of water temperatures in deg. Celsius
gas
String for gas code. Valid inputs include: He, O2, CO2, CH4, SF6, N2O, Ar, and N2
Value
Schmidt number (unitless)
Note
Temperature range is only valid from 4-35 deg Celsius
