About this calculator: Computes water-in-oil dispersion quality per ISO 3171 Annex A using ZTMX static mixer element characteristics. Results include droplet size (Hinze equation), settling rate (Stokes law), concentration ratio, and flow analysis across temperature ranges. Select a crude oil type to auto-populate density, viscosity, and interfacial tension at the specified temperature. For detailed product information, see the ZTMX Static Mixer page.
