STEP 0: Pre-Calculation Summary

Formula Used

Drag Force = 3*pi*Dynamic Viscosity*Settling Velocity*Diameter
F_D = 3*pi*μ_viscosity*v_s*D
This formula uses 1 Constants, 4 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Drag Force - (Measured in Newton) - Drag Force is the resisting force experienced by an object moving through a fluid.
Dynamic Viscosity - (Measured in Pascal Second) - The Dynamic Viscosity of a fluid is the measure of its resistance to flow when an external force is applied.
Settling Velocity - (Measured in Meter per Second) - Settling velocity is defined as the terminal velocity of a particle in still fluid.
Diameter - (Measured in Meter) - Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.

STEP 1: Convert Input(s) to Base Unit

Dynamic Viscosity: 10.2 Poise --> 1.02 Pascal Second (Check conversion here)
Settling Velocity: 1.5 Meter per Second --> 1.5 Meter per Second No Conversion Required
Diameter: 10 Meter --> 10 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_D = 3*pi*μ_viscosity*v_s*D --> 3*pi*1.02*1.5*10

Evaluating ... ...

what is drag force?

The drag force is the frictional force exerted by the fluid on any object when it is put into it.The drag depends directly on the size of the body. Since we are dealing with aerodynamic forces, the dependence can be characterized by some area.

How to Calculate Drag Force as per Stokes Law?

Drag Force as per Stokes Law calculator uses Drag Force = 3*pi*Dynamic Viscosity*Settling Velocity*Diameter to calculate the Drag Force, The Drag Force as per Stokes Law formula is defined that drag D is equal to the drag coefficient Cd times the density r times half of the velocity V squared times the reference area A. Drag Force is denoted by F_D symbol.

How to calculate Drag Force as per Stokes Law using this online calculator?
