Dear all,

any one can give information about mixed viscosity of the
crude oil along with the water

or if gas is present along with that mixture is there any changes would happen?
in mixture viscosity

regards,
dhns.

The viscosity of a liquid mixed with another (immiscible) one or with a solid (slurry) increases with the volume phase fraction irrespective of the viscosity or nature of the 2nd.
At first approximation the ratio of the mixture viscosity to that of the pure primary fluid is:
mu (mix)/ mu (primary)= 1 +2.5 * vol. fraction
This is the Einstein eq.
Other researchers have refined this equation with additional terms.

but this applies to suspansion of solids and not liquid/liquid dispersions (emulsions)
