The viscous force on an oil drop is measured to be equal to $3.0 \times 10^{-13} \mathrm{N}$ when the drop is falling through air with a speed of $4.5 \times 10^{-4} \mathrm{m} / \mathrm{s} .$ If the radius of the drop is $2.5 \times$ $10^{-6} \mathrm{m},$ what is the viscosity of air?
A fluid with a specific gravity of 0.92 has a kinematic viscosity of $5 \times 10^{-4} \mathrm{~m}^{2} / \mathrm{s}$ What is the dynamic viscosity of the fluid?
An air bubble of 1.0 -mm radius is rising in a container with vegetable oil of specific gravity 0.85 and viscosity $0.12 \mathrm{Pa} \cdot \mathrm{s} .$ The container of oil and the air bubble are at $20^{\circ} \mathrm{C} .$ What is its terminal velocity?
