Question

We have observed that water leaking from a pipe forms fountains. What conclusion can you draw from this observation?

• A. Water does not exert pressure on walls of the pipe.
• B. Water exerts pressure on walls of the pipe.
• C. Water exerts pressure in the middle of the pipe only.
• D. Water pressure decreases with an increase in density of the liquid.

Answer 1

The correct option is B Water exerts pressure on walls of the pipe.

Water is a fluid and just like any other fluid, it exerts pressure in all directions on the walls of the container. This is the reason why leaking water from pipes forms fountains.
