Is the following defination of stokes law correct :
The force that retards a sphere moving through a viscous fluid is directly proportional to the velocity & the radius of the sphere , the viscosity of the fluid.
Fcoeffecient of viscosity
Asked by sunil | 21st Nov, 2015, 09:58: PM
Yes, it is Stoke's law.
Stoke's found that when the body attains terminal velocity, the viscous force on the body is given by,
where, , r and v denote the coefficient of viscosity of the fluid, radius of the spherical body and the terminal velocity attained by the body.
