Lewicki-2-Parameter Moisture Sorption Isotherm
Description
Lewicki-2-Parameter MSI is a two-parameter sorption model that was developed based on Raoult's law, which assumes that water is present either as free water or as water of hydration.
Usage
Lewicki2MSI(WaterAct, AdsorpM, DesorpM)
Arguments
WaterAct |
the numerical value of Water Activity, which ranges from 0 to 1. |
AdsorpM |
the numerical value of the Moisture content of the Adsorption curve, which ranges from 0 to 1. |
DesorpM |
the numerical value of the Moisture content of the Desorption curve, which ranges from 0 to 1. |
Value
the nonlinear regression, parameters, and graphical visualization for Lewicki-2-Parameter model.
