Low shear viscosity
Web13 feb. 2013 · This study demonstrates the use of capillary rheology to measure viscosity profiles of motor oils up to high shear rates of 2,000,000 s -1. Viscosity profiles of oils at six different temperatures up to shear rates of ~ 2,000,000 s -1 are presented. The data sets at lower temperatures (100, 110, 120, 130 and 140 °C) are superposed on to the ... WebSurface shear viscosity of food emulsifiers may contribute appreciably to the long-term stability of food dispersions (emulsions and foams). In this work we have analyzed the structural, topographical, and shear characteristics of a whey protein isolate (WPI) and monoglyceride (monopalmitin and monoolein) mixed films spread on the air-water …

Web8 okt. 2015 · Shear viscosity is defined by the ratio of shear stress (ζ) to shear rate (γ): μ= ζ/γ The traditional unit for viscosity is the Poise (P), or 0.1 Pa-sec (also1 dyne-sec/cm2), where Pa¼Pascal. Drilling fluids typically have viscosities that are fractions of a Poise, so that the derived unit, the centipoise (cP), is normally used, where 1 cP=0.01 P=1 mPa-sec.

Web"Viscosity breakdown" is a phenomenon generated mainly by dilution of engine oil with fuel or the occurrence of places in the lubrication system that strongly shear the oil film and at the same time viscosity modifier polymers (at which the main bonds between molecules break) reducing their effectiveness in maintaining a high viscosity index. WebBoth hematocrit and plasma viscosity influence blood viscosity. The shear thinning property of blood is mainly attributed to red blood cell (RBC) rheological properties. RBC …
