Calculation and Error Analysis of Contaminated Viscosity in the Batch Transportation

According as GB 265—88《Petroleum products—Determination of kinematic viscosity and calculation of dynamic viscosity)), kinematic viscosity of contaminated product of differential oil products is determined and the first-hand measured data is acquired.Error of computational formulae about contaminated viscosity which is put forward by Soviet Russia scholars is analyzed, and a new computational formula is proposed.Compared with other formulae, a new formula is applied to calculate contaminated viscosity and satisfactory results can be obtained.
