The terminal velocity of a sphere of radius R, falling in a viscous fluid, is proportional to

The terminal velocity V of a spherical ball of lead of radius R falling through a viscous liquid varies with R such that

The terminal velocity of a sphere moving through a viscous medium is :

Give an example for a force proportional to velocity . Prove that terminal velocity of a solid object moving in a viscous medium is directly proportional to square of its size and inversely proportional to the viscoisity of the medium.

Define terminal velocity and obtain an expression for the terminal velocity in case of a sphere falling through a viscous liquid. Also show graphically the variation of velocity with time.

When a sphere falling in a viscous fluid attains a terminal velocity, then

Define terminal velocity. Show that the terminal velocity upsilon of a sphere of radius r, density rho falling vertically through a viscous fluid of density sigma and coefficient of viscosity eta is given by upsilon = 2 / 9 ((rho - sigma)r^2 g) / eta Use this formula to explain the observed rise of air bubbles in a liquid.

The terminal velocity of small sized spherical body of radius r falling vertically in a viscous liquid is given by the following proportionality

After terminal velocity is reached the acceleration of a body falling thorugh a viscous fluid is:
