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