  5. 1-107-S-ClothDry

    27 Apr 2019 | Modeling Scenarios | Contributor(s): Brian Winkel

    We build a mathematical model for the rate at which drying takes place in a cloth wet with water while hanging in air. A model can be based on underlying physical principles. Such a model is called an analytic model. Or your model could be based on observations and reasoned terms in your...
