alleryHydraulic pressure at depth h below liquid surface (density ρ):
AP_atm + ρgh (absolute) or just ρgh (gauge)
Bgh
Cρgh
Dρ/h
Answer & Solution
Correct answer: A. P_atm + ρgh (absolute) or just ρgh (gauge)
**Hydrostatic pressure:** P = P_atm + ρgh.
Independent of cross-sectional area.
Foundation of barometers and hydraulics.
