Chapter 15: Problem 10

It's not possible to breathe through a snorkel from a depth greater than a meter or so. Why not?

Short Answer

Expert verified
The reason you can't breathe through a snorkel beyond a depth of about a meter is due to the increased water pressure against which your lungs must work to inhale air. Beyond that depth, the pressure becomes too great for the human lungs to overcome, making it difficult if not impossible to breathe.

Step by step solution

01

Understanding Water Pressure

The deeper one goes under water, the greater the water pressure becomes. This is because water is much denser than air, and the weight of the water above exerts pressure on the water below. For every 10 meters you go down, the pressure increases by 1 atmosphere.
02

Understanding Lung Capacity

The human lungs work against atmospheric pressure to inhale and exhale air. When we breathe in, the diaphragm contracts creating a partial vacuum which allows the atmospheric pressure to push air into our lungs.
03

Combining the Concepts

When snorkeling, you are essentially breathing air from the surface. But if you go deeper, the water pressure increases, meaning your lungs would have to work against a pressure greater than 1 atmosphere to inhale air. Beyond a depth of about 1 meter, this becomes difficult if not impossible for the human lungs to overcome, hence why you cannot breathe through a snorkel beyond this depth.
