In this work, we develop a proxy high-throughput viscometer for Newtonian fluids with viscosities between 1500 and 12 000 cP.

Purpose of research . Development theoretical premises for the new inertial viscometer, as well development an approximate model viscosity fluid flow using convolutional neural networks and laser speckle contrast imaging data. Methods The study consists two parts. first is devoted to a in toroidal channel еру viscometer. mathematical includes dimensionless equations Navier-Stokes convective hea...

This paper presents the fabrication and testing of a simple and portable viscometer for the measurement of bulk viscosity of different Newtonian fluids. It is aimed at making available the instrument in local markets and consequently reducing or eliminating the prohibitive cost of importation. The method employed is the use of a D.C motor to rotate a disc having holes for infra-red light to pas...

A symmetrical BODIPY-BODIPY dyad with a diyne linker was prepared in two steps; the lifetime decay of this rotor appeared to correlate with the viscosity of the media, thus making this dyad a suitable small molecule viscometer for molecular solvents. The potential of using the rotor to probe the viscosity of ionic liquids was also investigated.

Summary The barrier material is a crucial component for wells, as it provides mechanical support to the casing and prevents uncontrolled flow of formation fluids, ensuring zonal isolation. One essential prerequisites success cementing an oil gas well efficient removal in-situ fluids their adequate replacement by material. quality mud displacement affected both density viscosity hierarchy among ...

(7) was determined on plasma, serum, and Ringer suspensions of erythro-cytes from five mammalian species with different mean corpuscu-lar volume (MCV) : elephant 112 pa, man 90 p3, dog 74 pa, sheep 37 p3, and goat 18 p3. Samples with cell percentages (H) ranging from 5% to maximum packing were tested with a modified version of GDM viscometer at 37 C and shear rates ($ from 52 to 0.052 set-? In ...
