Viscous Force

Equation and meaning

\[F = 6 \cdot \pi \cdot \eta \cdot rv\]

Viscous Force Where : F is the Force,η is the Viscosity of Fluid,v is the Terminal Velocity,r is the Radius,

Variables in this formula

eta — Eta
Enter this value unless it is the selected unknown.
F — Force
Force SI unit: N
rv — Rv
Enter this value unless it is the selected unknown.

How to use this calculator

  1. Leave one value emptyThe empty field is automatically treated as the unknown.
  2. Enter known values and unitsChoose N, kgf, dyn, SI or another compatible unit when available.
  3. Review the automatic answerThe result appears immediately and is substituted back into the formula to check the residual.
