Task 11004.
The resistance force acting on the vapor bubble rising in the liquid is determined by the Stokes formula Fc = 6nRnv, where R is the radius of the bubble; N is the viscosity coefficient of the liquid; V is the velocity of the bubble. Determine the coefficient of viscosity of the liquid, if R = 3 mm, and the velocity of the bubble is constant and equal to v = 0.02 m / s. The vapor density is assumed to be negligibly small in comparison with the density of the liquid 1 g / cm3.
A detailed solution with a brief description of the condition, formulas and laws used in the solution, the derivation of the formula and the answer.
If you have any questions about the solution, write. I try to help.
