Which of the following is the approximate total load at the bottom of a fully submerged 5-foot wall?

Question

Quizplus · Accepted Answer

The approximate hydrostatic pressure at the bottom of a fully submerged 5-foot wall is 937.5 pounds/foot of wall.
Solution: Use the triangular loading method to determine hydrostatic pressure
Given, 1 cubic foot of water = 62.5 pounds
Pressure (load) at water surface = 0
Step 1: Hydrostatic pressure at base of wall (5' deep)
= 62.5 pounds/cubic foot (pcf) *5 feet = 375 pounds/square foot (psf)
Step 2: Total load = ½ bh
= ½ (5 feet)(375 psf) = 937.5 pounds/foot
