KuhnMSI: Kuhn Moisture Sorption Isotherm

In PUPMSI: Moisture Sorption Isotherm Modeling Program

Kuhn Moisture Sorption Isotherm

Description

Kuhn Isotherm is a two-parameter model which contains many defining characteristics wherein each surface site has a different adsorption potential, as well as cluster formations on each site due to increase in partial pressure.

Usage

KuhnMSI(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 the Kuhn Moisture Sorption Isotherm model.
