Easily calculate the drag force on a spherical object moving through a viscous fluid using our Stokes Law Calculator. Input the fluid's dynamic viscosity, the sphere's radius, and its relative velocity to get instant results, crucial for understanding sedimentation, fluid dynamics, and particle movement in liquids or gases.
Formula:
The formula for Stokes' Law, calculating drag force on a sphere, is:
Fd = 6πμrv
- Fd: Drag force (Newtons, N)
- π: Pi (approximately 3.14159)
- μ: Dynamic viscosity of the fluid (Pascal-seconds, Pa·s)
- r: Radius of the spherical object (meters, m)
- v: Relative velocity of the sphere with respect to the fluid (meters per second, m/s)
