A instrument using Stokes’ Legislation calculates the drag pressure on a small spherical object transferring by means of a viscous fluid. For instance, it will possibly decide the resistance skilled by a sediment particle settling in water or the rate of a sphere falling by means of oil. Enter parameters sometimes embrace the sphere’s radius, the fluid’s viscosity, and the thing’s velocity or the gravitational acceleration.
Such computations are elementary in various scientific and engineering disciplines. Understanding fluid resistance is essential for designing devices like viscometers, analyzing particle sedimentation charges in geological research, and modeling microfluidic gadgets. The underlying precept, derived by Sir George Gabriel Stokes within the mid-Nineteenth century, gives a foundational understanding of low Reynolds quantity fluid dynamics.
