what is the speed of ejection of the liquid through the holes ?
In Millikan’s oil drop experiment, what is the terminal speed of an uncharged drop of radius 2.0×10^−5 m and density 1.2×10^23 kgm^−3 . Take the viscosity of air at the temperature of the experiment to be 1.8×10^−5 Pas. How much is the viscous force on the drop at that speed ? Neglect buoyancy of the drop due to air.

A tank with a square base of area 1.0 m^2 is divided by a vertical partition in the middle. The bottom of the partition has a small-hinged door of area 20 cm^2 . The tank is filled with water in one compartment, and an acid (of relative density 1.7) in the other, both to a height of 4.0 m. compute the force necessary to keep the door close.

What is the excess pressure inside a bubble of soap solution of radius 5.00 mm, given that the surface tension of soap solution at the temperature (20^o C) is 2.50×10^−2 N/m ? If an air bubble of the same dimension were formed at depth of 40.0 cm inside a container containing the soap solution (of relative density 1.20), what would be the pressure inside the bubble ? (1 atmospheric pressure is 1.01×10^5 Pa)
