उत्तर
This diagram illustrates that pressure of liquid increases with depth. The hole at greater depth has more pressure and hence the flow of liquid from there is more. Other hole is at less depth so the pressure of liquid there is less and hence the flow of liquid from there is less. So the diagram shows that pressure increases with an increase in depth.
