This calculation evaluates the restoration performance of dehydrated products such as freeze-dried powders by modeling moisture uptake kinetics and capillary-driven wicking. Engineers use these metrics to predict reconstitution time, equilibrium rehydration ratio, and the influence of pore structure on wetting behavior, which are critical for quality control in food and pharmaceutical processing.
