Final answer:
The absolute pressure at 33 feet in sea water can be calculated by adding the atmospheric pressure to the gauge pressure. To convert the gauge pressure to atmospheres absolute, divide it by 14.7.
Step-by-step explanation:
The absolute pressure at 33 feet in sea water can be calculated by adding the atmospheric pressure to the gauge pressure. The atmospheric pressure is typically 14.7 psi (pounds per square inch) or 1 atmosphere (atm). So, to find the absolute pressure in terms of atmospheres absolute, we can use the formula:
Absolute Pressure (in atm) = Gauge Pressure (in atm) + Atmospheric Pressure (in atm)
Since the atmospheric pressure is 1 atm, we just need to convert the gauge pressure to atmospheres absolute. To convert psig (pounds per square inch gauge) to atm, we use the conversion factor:
1 atm = 14.7 psig
Therefore, if the gauge pressure at 33 feet in sea water is known, we can divide it by 14.7 to get the absolute pressure in terms of atmospheres absolute.
