Viscosity is a measure of a fluid's resistance to flow. It determines how easily a fluid can move and deform under applied stress.

Common units of measurements for viscosity include Pascal-seconds (Pa·s), poise (P), and centipoise (cP).

• Viscosity is crucial in understanding fluid dynamics and designing efficient systems
• It is essential in various industries such as oil and gas, food processing, and pharmaceuticals
• Viscosity affects the performance of lubricants, paints, and coatings
