Stokes law: Contents Physics Topics such

Contents Physics Topics such as mechanics, thermodynamics, and electromagnetism are fundamental to many other scientific fields. What is the Formula for Terminal Velocity? Terminal Velocity of a Body in a Viscous Medium and Stokes’ Law When a body falls through a viscous medium (liquid or gas), it drags a layer of the fluid adjacent to […] Using Stokes’ Law provided in the lab manual, determine the viscosity (m) of the fluid using the average velocity of the three spheres. A common unit of viscosity is the Poise, or 1 g/cm.s. What is Stoke’s Law ? Stoke’s Law is a mathematical equation that expresses the settling velocities of the small spherical particles in a fluid medium. The law is derived considering the forces acting on a particular particle as it sinks through the liquid column under the influence of gravity. The force that retards a sphere moving through a viscous fluid is directly proportional to the velocity and the radius of the sphere, and the fluid’s viscosity.
