ISO flow cup is a commonly used liquid flow measurement device, usually used to measure the flow speed and viscosity of a liquid to determine its viscosity grade. It is a standard developed by the international standards organization (ISO), hence the name. ISO flow cup usually consists of a ...
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
Dear Lakeat; turbulent viscosity is related to turbulence modeling and based on some assumptions but it still has a physical meaning. In Laminar flows diffusion in flow field is characterized by molecular viscosity. But, turbulent flows in its nature consists random velocity fluctuations which intensi...
A new recorded presentation from Malvern Instruments compares the use of Dilute Solution Viscometry (DSV) with that of traditional glassware for measuring polymer intrinsic viscosity. Intrinsic viscosity correlates directly with molecular weight, which is a critical variable for polymers due to its ...
Taste, too, boils down simply to using appropriate chemical sensors. If you want to build a food-tasting robot, apH meterwould be a good starting point, perhaps with something to measure viscosity (how easily a fluid flows). Then again, if you've already given your robot eyes and a nose...
or sticky – properties that may be undesirable for hair products yet, on the other hand, desirable for other applications. In either case, there is a requirement to measure these properties in order to control and monitor them. There are two measurements to be taken into account when achievin...
Viscosity: Accurately weigh 15g of the substance (calculated on an anhydrous basis) and place it in a conical flask. Add 85g of acetone-water (249:1) solution and shake until completely dissolved. Measure the kinematic viscosity using capillary viscometer with different internal diameters, ensuring...
Stating an oil’s viscosity is meaningless unless the temperature at which the viscosity was measured is defined. Typically, the viscosity is reported at one of two temperatures, either 40°C (100°F) or 100°C (212°F). For most industrial oils, it is common to measure kinematic viscosity...
for Lubrizol, explains that viscosity is a measure of how things flow —“the degree to which a fluid resists flow under an applied force,” or “the power of resisting a change in the arrangement of the molecules.” A solid would have infinite viscosity, he says — a gas, very little...
How to measure kinematic viscosity? Convert joules to kilowatt hours What SI unit is used to measure mechanical energy? How to find the density of an object? What is the density in g/mL of a sphere with a diameter of 4.00 cm and a mass of 1.35 g?
