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.
