Utilize the Poise-Stokes Converter to quickly determine drag force on a sphere, fluid dynamic viscosity, or its terminal velocity. This essential tool applies Stokes' Law, simplifying complex fluid dynamics calculations for engineers, students, and scientists. Easily convert Poise viscosity units and analyze particle sedimentation with precision.
Formula:
The Poise-Stokes Law (often referred to as Stokes' Law for drag force) describes the drag force on a small spherical object moving through a viscous fluid at low Reynolds numbers. The formula is:
Fd = 6πηrv
- Fd: Drag force (dynes)
- η (eta): Dynamic viscosity of the fluid (Poise)
- r: Radius of the sphere (cm)
- v: Terminal velocity of the sphere (cm/s)
