Q

What pressure must a spring buoy, moored at a 500 foot depth, withstand?

🔍 Key Concepts

• Hydrostatic pressure increases with depth in seawater • Approximate pressure increase of 0.445 psi per foot of seawater depth • Difference between psig (gauge pressure) and total (absolute) pressure including atmospheric

💭 Think About

• How can you estimate the water pressure at 500 feet using a psi-per-foot approximation instead of full formulas? • Once you estimate the pressure from the water column alone, how do you compare that value with the multiple-choice answers that are given in psig? • Do you need to add atmospheric pressure to the calculated hydrostatic pressure when the question specifically asks for psig?

✅ Before You Answer

• Confirm the pressure-per-foot factor you’re using is appropriate for seawater, not freshwater • Be clear that psig already excludes atmospheric pressure, so it refers only to the gauge (water) pressure • After calculating, check which option your result is closest to among the choices provided
