Calculate the velocity with which the liquid gushes out of the `4cm^(2)` outlet, if the liquid flowing in the tube is water and liquid in `U` tube has a specific gravity `12`. Velocity of liquid at point `A` is `sqrt(20.2)m//s`

The velocity of liquid flowing through a tube at certain distance from the axis of tube

The velocity of liquid flowing through a tube at certain distance from the axis of tube

The velocity of liquid flowing through a tube at certain distance from the axis of tube

Why does the velocity increase when liquid flowing in a wider tube enters a narrow tube ?

In turbulent flow the velocity of the liquid molecules in contact with the walls of the tube.

In turbulent flow the velocity of the liquid molecules in contact with the walls of the tube.

In turbulent flow the velocity of the liquid molecules in contact with the walls of the tube.

A U-tube of uniform cross section (see figure) is partially filled with a liquid I. Another liquid II which does not mix with liquid I is poured into one side. It is found that the liquid levels of the two sides of the tube are the same, while the level of liquid I has risen by 2cm. If the specific gravity of liquid I is 1.1, the specific gravity of liquid II must be
