(a) Gauge pressure (pressure solely due to the weight of the water), P = ρ g d
(b) P = 1030 kg/m3 x 9.8 m/s2 x 0.15 m = 1514.1 Pascals
(c) F = PxA = ρ g d (π r2) = π r2 ρ g d

KHomework Set 9 Pressure on a Dam As the reservoir behind a dam is filled with water, the pressure that the water exerts on the dam increases Eventually, the force on the dam becomes substantial and it could cause the dam to collapse. There are two significant issues to be considered: First, the base of the dam should be able to withstand the pressure pgh , where p is the density of the water behind the danm h is its...
