How much pressure will a diver experience at a depth of 176 fsw?

To determine the pressure a diver experiences at a specific depth, it's important to understand how pressure increases with depth underwater. At sea level, atmospheric pressure is approximately 14.7 psi. For every 33 feet of seawater, pressure increases by an additional 1 atmosphere (ata), or roughly 14.7 psi.

At a depth of 176 feet, the pressure can be calculated as follows:

1. Calculate the increase in pressure due to the water depth:

• 176 feet divided by 33 feet per ata gives approximately 5.33 ata of pressure from the water itself.

2. Add the atmospheric pressure at sea level to find the total pressure:

• 5.33 ata from the water plus 1 ata from the atmosphere results in about 6.33 ata.

3. Convert atmospheres to psi:

• Multiplying the total ata (6.33) by 14.7 psi/ata gives approximately 93.00 psi.

It's important to consider that the option provided, 43 psi, could be a misunderstanding of the way pressure is calculated in this context. However, the vital aspect to note is that for accurate pressure understanding, a combination of water depth and the ambient atmospheric pressure at
