What factors affect viscosity? Viscosity is influenced by several factors: Temperature: Generally, higher temperatures decrease the viscosity of liquids. Pressure: In most liquids, higher pressure increases viscosity. Fluid Composition: The chemical makeup and additives can alter viscosity.
Factors Affecting Viscosity. The viscosity of liquids decreases quickly with an increase in temperature. On the other hand, the viscosity of gases increases with an increase in temperature. Thus, liquids flow more smoothly upon heating, and gasses flow more sluggishly.
Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow.
Viscosity is a fluids resistance to flow. This page details why certain liquids flow easily while others are slow as molasses.
In this section, we will investigate what factors, including viscosity, affect the rate of fluid flow. The precise definition of viscosity is based on laminar , or nonturbulent, flow. Before we can define viscosity, then, we need to define laminar flow and turbulent flow.
Viscosity may also depend on the fluid's physical state (temperature and pressure) and other, external, factors. For gases and other compressible fluids , it depends on temperature and varies very slowly with pressure.
factors affecting viscosity. This part needs to be reorganized. Viscosity is first and foremost a function of material. The viscosity of water at 20 °C is 1.0020 millipascal seconds (which is conveniently close to one by coincidence alone).
