The accuracy of estimation ETP-46464 encouraging from the viewpoint of engineering application. For the emulsions of all crudes and at all temperatures and shear rates, the maximum average AAD based on a shear rate is 9.4% in part 2, and the maximum average AAD based on a shear rate is 17.9% in part 1, i.e. the first 20 s.
