The terminal velocity of fall of lead shots in the cylindrical vessel is influenced by the nearness of the walls of the vessel. Hence the velocity in formula is divided by a factor open parentheses 1 plus fraction numerator 2.4 r over denominator R end fraction close parentheses . Where r is the radius of the lead shots and  the radius of the vessel. This is called
