State and prove stokes law dimensionally
WebThe flow rate depends on the fluid’s viscosity, the cross-sectional dimensions of the pipe, and the pressure gradient. Poiseuille's law can be determined from a simple procedure involving dimensional analysis. Poiseuille’s law describes flow rate in a pipe and applies to areas like fluid flow in a capillary tube. WebPhysicists often use square brackets around the symbol for a physical quantity to represent the dimensions of that quantity. For example, if r r is the radius of a cylinder and h h is its height, then we write [r] = L [r] = L and [h] = L [h] = L to indicate the dimensions of the radius and height are both those of length, or L. Similarly, if we use the symbol A A for the …

In 1851, George Gabriel Stokes derived an expression, now known as Stokes' law, for the frictional force – also called drag force – exerted on spherical objects with very small Reynolds numbers in a viscous fluid. Stokes' law is derived by solving the Stokes flow limit for small Reynolds numbers of the … See more The force of viscosity on a small sphere moving through a viscous fluid is given by: $${\displaystyle F_{\rm {d}}=6\pi \mu Rv}$$ where: • Fd … See more Steady Stokes flow In Stokes flow, at very low Reynolds number, the convective acceleration terms in the Navier–Stokes equations are neglected. Then the flow equations become, for an incompressible steady flow: See more • Einstein relation (kinetic theory) • Scientific laws named after people • Drag equation • Viscometry See more Stokes' law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube.

The formula comes from substracting the position at time (t-1) seconds. Then : x t − x t − 1 = v 0 ( 1 s) + 1 2 a ( 2 t − 1 s) ( 1 s). As you can see we generally skip writing the units. So dont do it. Additionally the equation is now dimensionally correct.
