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...
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 ...

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...
Also known as donut load cell or washer load cell, thru-hole load cells traditionally have a smooth non-threaded inner diameter used to measure compressive loads that require a rod to pass through its center. One of the primary uses of this sensor is to measure bolt loading. Typical applicat...
How to Measure the Melting Point in the Chemistry Lab By WonderHowTo Mar 22, 2022 Science Experiments WonderHowTo Find out how everything in a chemistry lab works, from pipettes to burners to recrystallization to storage. You'll get precise instructions on how to work and perform certain ...
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
viscosity correlates directly with molecular weight, which is a critical variable for polymers due to its controlling influence on processability and the mechanical properties of the final product. Intrinsic viscosity is therefore used as part of the specification for many commodity and engineering ...
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...
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 ...
