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.
