What does your textbook say about 6. VISCOSITY OF A LIQUID BY STOKE’S METHOD?
AIM To determine the co-efficient of viscosity of the given liquid by stoke’s method APPARATUS REQUIRED A long cylindrical glass jar, highly viscous liquid, metre scale, spherical ball, stop clock, thread. FORMULA η δ σ r g ( ) N s m - where η - Coefficient of viscosity of liquid ( N s m – ) r → radius of spherical ball ( m ) δ → density of the steel sphere ( kg m – ) σ → density of the liquid ( kg m – ) g → acceleration due to gravity ( . m s – ) V → mean terminal velocity ( m s – )
