The Reynolds number is computed with the diameter of a sphere having the same volume. The shape factor cannot exceed a value of 1.
Web24. jún 2024 · The drag coefficient is a dimensionless number that characterizes all of the complex factors that affect drag. The drag coefficient is usually determined … Web2. feb 2024 · For a spherical object of radius r, the magnitude of the drag force is given by Stokes equation. F D = 6π η r v F D = 6 π η r v This kind of resistance where the liquid’s viscosity plays an important role is called the viscous drag force. Stokes equation is used to study small particles suspended in a liquid. Application of Drag Force
In 1851, George Gabriel Stokes derived an expression, now known as Stokes' law, for the frictional force – also called drag force – exerted on spherical objects with very small Reynolds numbers in a viscous fluid. Stokes' law is derived by solving the Stokes flow limit for small Reynolds numbers of the … Zobraziť viac The force of viscosity on a small sphere moving through a viscous fluid is given by: $${\displaystyle F_{\rm {d}}=6\pi \mu Rv}$$ where: • Fd … Zobraziť viac Steady Stokes flow In Stokes flow, at very low Reynolds number, the convective acceleration terms in the Zobraziť viac • Einstein relation (kinetic theory) • Scientific laws named after people • Drag equation • Viscometry Zobraziť viac Stokes' law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube.

Web24. máj 2024 · A body that moves relative to a surrounding fluid thus experiences a frictional force. This frictional force is also called flow drag. In general, the drag force F d of a body can be calculated with the following formula: (1) F d = 1 2 ρ v ∞ 2 A c d In this formula ϱ denotes the density of the fluid, i.e. the denser the fluid, the greater the drag.
