What is falling sphere resistance method?

The falling ball viscometer typically measures the viscosity of Newtonian liquids and gases. The method applies Newton's law of motion under force balance on a falling sphere ball when it reaches a terminal velocity.

How does a falling ball viscometer work?

The classic falling-ball viscometer works according to the Hoeppler principle. It measures the time a ball takes to move through the sample liquid. To obtain viscosity values, a calibration with a viscosity reference standard and the sample's density is required.

How to Calculate Drag Force in Falling Sphere Resistance Method?

Drag Force in Falling Sphere Resistance Method calculator uses Drag Force = 3*pi*Viscosity of Fluid*Velocity of Sphere*Diameter of Sphere to calculate the Drag Force, Drag Force in Falling Sphere Resistance Method, the drag force is the resistance exerted by the fluid on the sphere as it falls. It is determined by the sphere's velocity, fluid viscosity, and sphere size. At terminal velocity, the drag force equals the gravitational force minus the buoyant force. Drag Force is denoted by F_D symbol.
