WebA rheometer is a lab device used to measure the viscosity of fluids (how thick or sticky a fluid is -- think water vs. honey). There are certain rheometers that can measure the viscosity of fluids by measuring the response of a vibrating system submerged in a fluid. WebThe measured time is an indicator for viscosity (due to the velocity of flow depending on this quantity). To obtain kinematic viscosity (v = ny), multiply the measured flow time (t f) by the so-called capillary constant (K C). This constant needs to be determined for each …

WebDec 20, 2024 · Rotational Viscometer. The rotational viscometer measures the torque required to turn an object in a fluid as a function of that fluid’s viscosity. This method is frequently used in quality control, and in production laboratories. Simple liquids react in a simple way to flow speed and time, and are called pure or Newtonian fluids. WebMay 25, 2024 · That means that the SRV operates on the high-shear tail of the shear rate curve. The viscosity that it indicates is significantly lower than for most other non-vibrational viscosity measurement processes. When measured with a Rheonics SRV viscometer, the fabric softener gives an indicated viscosity of 9.7 cPs. generac with battery backup
