Lewicki2MSI: Lewicki-2-Parameter Moisture Sorption Isotherm

In PUPMSI: Moisture Sorption Isotherm Modeling Program

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.
