A tank is filled with water. There is a hole in . the bottom. At the bottom total pressure is $3\, atm$, then, the velocity of water flowing from h $ \left( \text{1atm }=\text{1}{{0}^{5}}\text{ N}/{{\text{m}}^{\text{2}}} \right) $ ,then, the velocity of water flowing from hole is

At what speed, the velocity head of water is equal to pressure head of $40 \,cm$ of $Hg$?

An open U-tube contains mercury. When $11.2 \,cm$ of water is poured into one of the arms of the tube, how high does the mercury rise in the other arm form its initial level?

If two soap bubbles of different radii are connected by a tube:

If the work done in blowing a bubble of volume $V$ is $W$, then the work done in blowing a soap bubble of volume $2\, V$ will be :

A rain drop of radius $0.3\, mm$ has a terminal velocity of $1\, m / s$ and the viscosity of $1\, m / s$ and the viscosity of air is $18 \times 10^{-5}$ poise. The viscous force on the drop is:
