An air bubble of radius 1 cm is found to rise in a cylindrical vessel of large radius at a steady rate of `0.2` cm per second. If the density of the liquid is 1470 kg `m^(-3)`, find its viscosity. Take `g=9.8ms^(-2)`

an air bubble of radius 1mm is allowed to rise through a long cylindrical column of a viscous liquid and travels at a steady rate of 2.1cm/s if the density of the liquid is 1.47gm/cc find its viscosity. Assume g=980cm/ s^2 and neglect the density of air.

An air bubble of radius 1 mm is allowed to rise through a long cylindrical column of a viscous liquid of radius 5 cm and travels at a steady rate of 2.1 cm per sec. if the density of the liquid is 1.47(g)/(c c) . Its viscosity is nearly (n)/(2) poise. Then find the value of n. Assume g=980(cm)/(sec^(2)) and neglect the density of air.
