getSchmidt {LakeMetabolizer}

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
