Viscosity is a scientific term that describes the resistance to flow of a fluid. The fluid can be a liquid or a gas, but the term is more commonly associated with liquids. As a simple example, syrup has a much higher viscosity than water: more force is required to move a spoon through...
Is high viscosity thick or thin? Fluids with high viscosities are often characterized by their strong intermolecular forces, they exhibit very high internal friction by resisting the motion of the flow, such fluids possess a thick consistency. What is the SI unit of viscosity? Newton-seconds per...
all fluids have positive viscosity, and are technically said to beviscousorviscid. However, a liquid is said to be viscous if its viscosity is substantially greater than water's, and may be described as mobile if the
Viscosity techniques are very popular because they are experimentally simple. They are, however, less accurate and the determined molecular weight, the viscosity average molecular weight, is less precise. For example, Mv depends on a parameter which depends on the solvent used to measure the viscosi...
viscosity = shear stress / shear rate The result is typically expressed incentipoise(cP), which is the equivalent of 1 mPa s (millipascal second). Shear stressis the force per unit area required to move one layer of fluid in relation to another. ...
This external force takes the form of a shear stress which is defined as the force acting over a unit area of fluid and results in a velocity gradient across the thickness of the sample termed the shear rate. The shear viscosity or dynamic viscosity related to this process is given by ...
is another way of defining viscosity.Dvdivideddrrepresents the "sheer rate," or the speed the liquid is moving. Thenis a constant unit equal to 0.00089Pa s(Pascal-second), which is a dynamic viscosity measurement unit. This law has some important practical applications such as inkjet printing...
which in this case would be the forces necessary to either move the plates apart or closer together. The shear stress is the shear force divided by a unit area and is expressed as newtons per square meter (N/m) or pascals (Pa). Viscosity calculations are usually performed in metric units...
