Question
How does pressure in liquids change with depth
Open in App
Solution
Liquid pressure = weight density x depth
When you swim under water, you can feel the water pressure acting against your eardrums. The deeper you swim, the greater the pressure. The cause of pressure is simply the weight of the water (and air) above pushing against you. If you swim twice as deep, there is twice the weight of water above, and twice the water pressure.
The pressure exerted by the liquid depends on density as well as depth. If you were submerged in a liquid more dense than water, the pressure would be proportionally greater.
