Microsoft Word - Bernoulli_PracticeProblems. Water is siphoned from a large tank through a constant diameter hose as shown in the figure. Determine the maximum height of the hill, Hhill, over which the water can be siphoned without cavitation occurring.
Worked Example Problems: Bernoulli’s Equation P1 ˆg +z 1 + V2 1 2g = P2 ˆg +z 2 + V2 2 2g The objective in all three of the following worked example problems is to determine the pressure at location 2, P 2. For all three problems the gravita-tional constant, g, can be assumed to be 9:81m=s2 and the density of water, ˆ, as 1000kg=m3. All ...
20 cze 2020 · p + 1 2ρ v2 + ρgh = konstant Bernoulli equation. Two states on a streamline are thus linked by the following equation: p1 + 1 2ρv21 + ρgh1 = p2 + 1 2ρv22 + ρgh2. In the following, different exercises for the application of the Bernoulli equation will be shown.
The Bernoulli equation is a mathematical statement of this principle. In fact, an alternate method of deriving the Bernoulli equation is to use the first and second laws of thermodynamics (the energy and entropy equations), ra-ther than Newton’s second law. With the approach restrictions, the general
Bernoulli differential equation can be written in the following standard form: dy. + P(x)y = Q(x)yn , dx where n 6= 1 (the equation is thus nonlinear). To find the solution, change the dependent variable from y to z, where. z = y1−n.

Discuss Bernoulli's equation in two special cases: (a) horizontal flow (y1 = y2) and (b) a static fluid (v1 = v2 = 0). A barrel full of rainwater has a spigot near the bottom, at a depth of 0.80 m beneath the water surface.
