Stokes Law and Terminal Velocity

No. Date Physics "Stoke's law and TermindL Velocity" When a small spherical body Falls In a long liqued Column then After Sometimes It falls with a constant Velocity. when asmall sphetical body Falls in a liquid column with termind Velocity then VISCOUS Force acting on His F= 6th TV Where T= Radus of the body V= = terminal Velocity n= Coeficient of Viscocity. This W called "Stoke's law" Terminal Velocity, V r"(p-o)g g n Where p= density of body O= density of liquid n= Coeficient of Viscolity of liquid g = Acceleration due to Gravity .

No. Date Importance of Stoke's law -. This law IS Used inthe deterMenation of electronic charge. - This law helps a man Coming down with the help of parachuse - This law account For the Formation of clouds. Ciffical Velocity Ctihcal Velocity Vc : kn rp Where. F= = Reynold number n = Coeficient of Viscocity ribe liquid r Radius of Capilarry Capilarty P= density of the liquid.
