Brookfield viscometer shear rate calculation
WebAug 27, 2024 · The third method (Method 3) in the literature used to calculate the apparent viscosity and shear rate was based on an empirical data treatment of the primary readings from the rotational viscometer, and two conversion factors used in the calculation were tabulated in the reference (Mitschka 1982). In this method, the shear stress for each ... WebShear Rate and Temperature Dependence. Objective: The objective of this lab is to become familiar with the use of a viscometer (Brookfield Couette Viscometer) in the determination of the molecular weight, shear rate, dilution and temperature dependence of viscosity for a series of polydimethylsiloxane (PDMS) polymers. Instruments to be used:

Webwhere ω = rate of rotation; α = cone angle (typically less than 5 degrees); M = torque; R = radius. Rotational viscometers are typically used over a shear rate range of 10 −2 –5 s −1. At higher rotational speeds, flow instabilities and deviations from the simple shear flow assumed in Eqs. (5.28) and (5.29) occur.

Web4.1.1.1 Coaxial Viscometer. The first high shear rate viscometer was designed by Merrill (1954), Figure 4.1, and was based on the coaxial viscometer. The viscometer applied high shear rates to the test fluid by rotating a spindle at very high speeds, which were achieved by connecting the spindle to a drill press.
