# write an activity to show that liquid pressure depends on its depth

Take an emty plastic bottle and make 4 holes at the same heights on different sides.Fill the bottle with water,We can see that water rushes out through all the holes with equal pressure.This simple activity shows that liquid exert equal pressure on the walls of the container at a certain depth

Pressure increases with depth. While you are swimming you feel the pressure of the water on your ear drums.
(inside the ear, the pressure is the same as it is at sea level, outside the water)
This pressure called the hydrostatic pressure is  created by the weight of all that water above the diver.

experiment
1. take any plastic bottle and make 3 holes in it with different heights fill the bottle with water
2. dont close the tap you will notice that thewater comes more from  lower hole

Take a tall can. Drill three equal small holes in its side at different heights from bottom. Fill the can with water qnd observe. Water rushing out from the lowest hole goes furthest;that frim the highest hole falls nearest and that from the middle hole falls in between the two. This shows that the pressure if water in the can is greatest near the lowest hole and least near the uppetmost hole. Thus the pressure due to liquid increases with depth from the surface of the liquid.

Water squirts further at greater depths

### Steps

1. Punch holes in side of the container at one inch intervals.
2. Fill the container with water.
3. Measure the distance from the container that the water squirts out of each hole.
4. Plot a graph of depth (distance of hole from top of water level) versus distance water squirts from can.

### Keep records

If this is going to be an experiment for a science fair, you will need to record your activities in a log book.

### Draw conclusions

This experiment should verify that since the water squirts out further with increasing depth, that the water pressure increases with depth.

Density of the liquid, and the acceleration due to gravity. For any given liquid with constant density throughout, pressure increases with increasing depth. this is how the pressure of liquid depends on its depth.
