What is the bottom pressure for a diving depth of 120 feet of seawater?

To determine the bottom pressure at a diving depth of 120 feet of seawater, we need to calculate the pressure exerted by the water at that depth. The pressure due to water can be calculated using the formula:

Pressure (psi) = Depth (ft) × 0.433 psi/ft + Atmospheric Pressure

At sea level, atmospheric pressure is approximately 14.7 psi. The pressure due to the column of seawater can be calculated using the conversion factor of 0.433 psi per foot of seawater.

Calculating the pressure from the depth:

• Pressure from seawater = 120 ft × 0.433 psi/ft = 51.96 psi.

Adding the atmospheric pressure:

• Total pressure = 51.96 psi + 14.7 psi = 66.66 psi.

However, examining the choices and potential misunderstandings, standard calculation for diving often considers the total pressure experienced by divers, and generally, the pressure is approximated for simplicity or standards in dive tables.

For recreational diving purposes, the common rounding points typically suggest around 1.5 times the depth in feet for an approximation scenario in diving scenarios, which interprets the condition differently depending on task and trust within drowning measures,
