Viscosity: Definition, Unit & Formula Sciencing

WebJun 9, 2024 · At room temperature, the dynamic viscosity of water is around 0.89 mPas, while at 20 degrees Celsius, the viscosity of water is approximately 0.01 poise or 10-3 Pa.s (Pascal seconds). Pascal-second (Pa.s) or newton-second per metre squared (N.s/m2) is the SI unit for dynamic viscosity. Informally, viscosity is the quantity that describes a fluid's resistance to flow. Fluids resist the relative motion of immersed objects through them as well as to the motion of layers with differing velocities within them. See more 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 … See more The the mathematical expression describing the flow of fluids in circular tubes was determined by the French physician and physiologist Jean Poiseuille (1799–1869). Since … See more Motor oil is like every other fluid in that its viscosity varies with temperature and pressure. Since the conditions under which most automobiles will be operated can be anticipated, the behavior of motor oil can be specified … See more The mathematical expression describing the viscous drag force on a sphere was determined by the 19th century British physicist George Stokes. I will not derive it here (but I probably should someday in the future). R = 6πηrv … See more how to start a workout routine

Difference Between Kinematic And Dynamic Viscosity - BYJU

WebViscosity (dynamic viscosity): The SI physical unit of dynamic viscosity (greek symbol: ) is the pascal - second (Pa·s), which is identical to 1 kg •m −1 •s −1. In France there have been some attempts to establish the poiseuille (Pl) as a name for the Pa·s but without international success. Care must be taken in not confusing the ...
