Abstract: The present invention relates generally to systems and processes for improved drag reduction estimation and measurement and more specifically to portable drag reduction analyzers and processes for upscaling drag reduction data for a variety of field applications. A drag reduction parameter ΔB for the fluid mixture is used for determining drag reduction for a fluid mixture in an oil field or pipeline operation.
