Water flows from the pipe shown in the figure with speed . What is the height of the standing column of water? 𝑨?=??𝑨?
(the flow path of the water), we can use Bernoulli’s equation, which statesP1+12ρv21+ρgh1=P2+12ρv22+ρgh2,(1)where the densityρis simply that of water. We can use this equation to relate the conditionsat Point 1 to those at Point 2.Specifically, we can use this to determine the pressure atPoint 1, findingP1=P2+12ρ(v22-v21) +ρg(h2-h1).(2)The densityρis simply that of water. The pressure at point 2, since the water is exposedto the air, is the atmospheric pressure
