To obtain accurate measurement results, it is important to understand the rheological properties of the product: - Newtonian Fluids (e.g., water): These liquids have a viscosity that does not change with variations in shear rate, meaning the viscosity remains the same at any speed. Only temp...
Ford viscosity cup is a device used to measure the viscosity of liquids, usually used to test the viscosity of liquid materials such as paints, Coatings, resins, glues, etc. Ford viscosity cup usually consists of a conical cup body and an outlet with a specific aperture. When the liquid in...
using a Ubbelohde viscometer. The measurement solution is usually a 2% aqueous solution with the formula: V = Kdt. V is the viscosity, the unit is mPa.s, K is the constant of the viscometer, d is the density at constant temperature, t is the time from the top to the bottom ...

In the viscosity test experiment, there is often a situation that the viscosity range of the unknown sample needs to be measured for the viscosity of the sample. How does the DV-79 digital viscometer correctly measure the viscosity value of the sample wi
Understanding the Wheatstone bridge circuit In order to measure the changes in resistance, the strain gauge must be connected to an electrical circuit that is capable of accurately responding to the changes and creating a differential voltage variation. Multiple strain gauges can be used in a divided...
How to Measure Wax Hardness/Stickiness The beauty of waxes is that they achieve hold yet are flexible; the perfect combination for hair styling. Wax is not water-soluble thus not prone to drying. What waxes do risk however is becoming too greasy, heavy, or sticky – properties that may be...

To calculate the amount of metabolic water produced by the retina, it is most convenient to measure the amount of oxygen consumed during the metabolism of glucose, from which the amount of metabolic water produced by aerobic metabolism within the retina can first be calculated using the basic pri...
Pitot tubes are used to measure airflow velocity, but advanced tunnels deploy laser anemometers that detect wind speed by "seeing" airborne particles in the airstream. Pressure probes monitor air pressure and water vapor pressure sensors track humidity. In addition to sensors, visual observations ...
