In gholtgrieve/gassyPants: Functions Useful for Working With Gasses Dissolved in Water

Description

Returns the temperture specific Schmidt number (Sc) for a given gas. Sc 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. Code taken almost verbatim from the Lake Metabolizer package (thanks guys!)

Usage

get.Sc(temperature, gas)

Arguments

temperature	Numeric vector of water temperatures in deg. Celsius
gas	String for gas code. Use "all" to get the full list of supported gasses.

Value

Schmidt number (Sc; unitless)

Note

Temperature range is only valid from 4-35 deg Celsius

get.Sc(temperature=12, gas="O2")
get.Sc(gas="all") #returns full list of supported gasses and their temperature coefficients
