The value of (Re, Oh) for a liquid for this map can be calculated using the liquid's density, surface tension and viscosity, characteristic length (d) and speed (v). As shown in the Results section, 𝑑 = 1 µm and 𝑣 = 10.55 m/s was obtained using trial and error methods, and they conformed well to the foaming prediction map for predicting foaming results from shake test experiments.
