What head in feet corresponds to 2 psi?

• A. 4.62 feet
• B. 2.31 feet
• C. 3.0 feet
• D. 5.0 feet

Answer: (A)

Think of pressure as the height of a water column it can support. For freshwater, every 1 psi of pressure equals about 2.31 feet of head. So 2 psi would be 2 × 2.31 ≈ 4.62 feet of head. You can see this from the basics: P = γh, where γ for water is about 62.4 lb/ft³. Converting 2 psi to pounds per square foot gives 2 × 144 = 288 lb/ft², and h = P/γ = 288 / 62.4 ≈ 4.62 ft.
