How Stoke's law is related here?

Stoke's law is the basis of the falling sphere viscometer, in which the fluid is stationary in a vertical glass tube. A sphere of known size and density is allowed to descend through the liquid.

What is buoyant force in viscous flow?

The buoyant force is a force act exactly opposite to gravitational force. The slower velocity of the ball moving thru liquid is due to the drag of viscous fluid. When we say weightlessness of the ball, it only means there is no force acting on the mass externally.

How to Calculate Buoyant Force in Falling Sphere Resistance Method?

Buoyant Force in Falling Sphere Resistance Method calculator uses Buoyant Force = pi/6*Density of Liquid*[g]*Diameter of Sphere^3 to calculate the Buoyant Force, Buoyant Force in Falling Sphere Resistance Method, the buoyant force is the upward force exerted by the fluid on the falling sphere. It is equal to the weight of the fluid displaced by the sphere. This force affects the sphere's terminal velocity and must be accounted for when calculating fluid viscosity. Buoyant Force is denoted by F_B symbol.

How to calculate Buoyant Force in Falling Sphere Resistance Method using this online calculator? To use this online calculator for Buoyant Force in Falling Sphere Resistance Method, enter Density of Liquid (ρ) & Diameter of Sphere (d) and hit the calculate button. Here is how the Buoyant Force in Falling Sphere Resistance Method calculation can be explained with given input values -> 79.98978 = pi/6*984.6633*[g]*0.25^3.
