Temperature dependence of the viscosity of water-fuel oil emulsions

The experimental dependence of the kinematic viscosity oil-water emulsions on temperature was examined. Oil-water with a high water content (up to 60%) were prepared by long-term mechanical stirring in cylindrical vessel using screw metal brushes. Stokes method used determine viscosity. Emulsions are opaque liquids. Therefore, movement ball's time between upper and lower layers liquid determined. At same time, there layer under emulsion tube. To measure at different temperatures, system placed larger flask through which heated pumped.
 As result, it experimentally shown that fuel oil is than (at temperatures). increases, its increases. In order meet conditions optimal sprey WOE (as well as other similar fuels), they must be temperatures higher those recommended for pure (non-emulsified) oil.
