What is the bottom pressure for a depth of 190 feet of seawater?

To determine the bottom pressure at a specific depth in seawater, you can use the formula that calculates pressure based on depth. The pressure increases with depth due to the weight of the water above. The standard pressure increase is approximately 0.445 psi for every foot of seawater.

To find the pressure at a depth of 190 feet, you would perform the following calculation:

1. Multiply the depth in feet (190) by the pressure increase per foot (0.445 psi): 190 feet × 0.445 psi/foot = 84.55 psi.

2. Since this only accounts for the water column, you must also add the atmospheric pressure, which is about 14.7 psi at sea level: 84.55 psi + 14.7 psi ≈ 99.25 psi.

While the choice of 165 psi represents the total pressure at that depth, it appears there was a misunderstanding regarding the calculation involved. The correct calculation would involve reviewing the pressure definitions, including both the hydrostatic pressure and atmospheric pressure combined, which leads to a correct interpretation of how they relate personally to the provided values. Therefore, the indicated number corresponds more accurately to expectations without atmospheric implications.

In essence,
