Shear force is necessary for fluid flow because it creates a differential in velocity within the fluid, allowing it to move from one point to another. This shear force helps overcome the internal friction in the fluid and facilitates the movement of fluid particles along a surface or past each other. In essence, shear force is responsible for driving the flow of fluids.

Scientific definition of viscosity?
Viscosity is a measure of a fluid's resistance to flow. It is the internal friction within a fluid that arises due to the interaction between its molecules. The higher the viscosity, the thicker the fluid and the more resistance it offers to flowing.
What is a Dilatant fluid?
A dilatant fluid, also known as a shear-thickening fluid, is a type of fluid that becomes thicker and more viscous when subjected to stress or shear forces. This is the opposite of most fluids, which become thinner and less viscous when stressed. An example of a dilatant fluid is a mixture of cornstarch and water.
What is meant by incompressible viscous fluid?
An incompressible viscous fluid is a fluid that does not change density when subjected to pressure and shear stress. In other words, its density remains constant under different pressures. Viscous fluid refers to the fluid's resistance to shear deformation or flow, indicating its thickness or stickiness.
What is the property of a fluid that represents it's resistance to flow?
Viscosity is the property of a fluid that represents its resistance to flow. It determines how easily a fluid can deform or flow under an applied force. High viscosity fluids flow more slowly than low viscosity fluids.
What the definition of retardation time in fluid?
Retardation time in fluid refers to the time it takes for a substance to pass through a porous medium slower than it would in free flow due to filtration and adsorption processes. It measures the rate at which solutes travel through porous materials, providing insights into the interactions between the solute and the porous medium.
What is shear flow?
Shear flow is the flow induced by a force gradient (for a fluid). For solids, it is the gradient of shear stress forces throughout the body.
What is the relationship between the shear g and the shear rate?
Viscosity is constant to the flow of the fluid.

What are rheometers used to measure?
A rheometer is used to measure the affects of an applied force to a fluid, slurry or suspension. The rheometer measures the flow of the fluid. There are two types of rheometers, shear rheometers and extensional rheometers.
What is frictional drag?
Friction drag is the drag acting on the surface of an object from a fluid flowing over it. When a fluid flows over an object it exerts a shear force on the object because of the fluid's viscosity which pulls the object in the direction of the flow.

What has the author Gregory Merlin Powell written?
Gregory Merlin Powell has written: 'The structure of velocity and density interfaces in a weakly turbulent stratified shear flow' -- subject(s): Fluid dynamics, Shear flow
What is the name of the thickness property of a fluid that creates boundary layers and shear stress?
The property is viscosity. Viscosity is the measure of a fluid's resistance to deformation or flow, which creates boundary layers and shear stress when fluid flows over a surface.
What is the driving force for fluid flow?
pressure gradient is
What is the flow of energy through a fluid?
Hydraulic force.
What is viscostity?
viscosity is the property of a fluid that resists the force tending to cause the fluid to flow.
