Question

A steel sphere of mass 500g is dropped freely in a viscous liquid,it reaches it terminal velocity in 04.second.if the viscous resistance force is 0.003times of the square of falling velocity calculate the terminalvelocity the sphere

Answer 1

Explanation:

Dynamic viscosity is related to kinematic viscosity by the equation μ = ρν where ρ is the density of the fluid. The unit of dynamic viscosity μ is centipoise. If fluid density ρ has the unit of g/cc, then kinematic viscosity ν has the unit of centistoke. Thus, 1 centistoke equals 1 centipoise divided by 1 g/cc.
