What pressure is experienced at a depth of thirty-three feet?

At a depth of thirty-three feet, the pressure experienced is 2 atmospheres. When considering how pressure increases with depth in water, a general rule of thumb is that for every 33 feet (approximately 10 meters) of seawater, the pressure increases by about 1 atmosphere.

At sea level, the atmospheric pressure is already 1 atmosphere. Therefore, when you go down to a depth of 33 feet, you add an additional atmosphere of pressure from the water above, bringing the total to 2 atmospheres.

This concept is critical for understanding underwater environments and is often used in fields such as oceanography and underwater acoustics, as pressure influences sound speed and other acoustic properties in the water column.
