The proportionality factor is the dynamic viscosity of the fluid, often simply referred to as the viscosity. It is denoted by the Greek letter mu (μ). The dynamic viscosity has the dimensions , therefore resulting …

Nov 21, 2025 · Viscosity is a major factor in determining the forces that must be overcome when fluids are used in lubrication and transported in pipelines. It controls the liquid flow in such processes as …

Learn how viscosity measures a liquid’s resistance to flow, why “thick” liquids like syrup move slowly, and how intermolecular forces and molecular structure impact flow rate.

Oct 18, 2024 · Viscosity is a physical quantity that describes a fluid’s resistance to flow. It is a property that resists the relative displacement of the different layers of the fluid. It can be considered as the …

Informally, viscosity is the quantity that describes a fluid's resistance to flow. Formally, viscosity is the ratio of shearing stress to velocity gradient.

Viscosity Definition The definition of viscosity is as follows: Viscosity is a measure of a fluid’s resistance to flow. The SI unit of viscosity is poiseiulle (PI). Its other units are newton-second per square metre …

Learn viscosity meaning, SI units, formula, types, and real-life applications. Master Class 11-12 Physics viscosity concepts with solved examples for 2025 exams.

Jul 23, 2025 · Viscosity is a fundamental property of liquids that describes their internal resistance to flow. Imagine three bowls—one filled with water and the other with oil and honey.

Learn about viscosity, what it means in physics and engineering, and the difference between dynamic and kinematic viscosity measurements.

Discover viscosity—its types, measurement, and role in mechanical engineering. Learn how it affects fluid flow and design.
