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 ...
Class: Bernoulli Equation Practice Worksheet. Problem 1. Water is flowing in a fire hose with a velocity of 1.0 m/s and a pressure of 200000 Pa. At the nozzle the pressure decreases to atmospheric pressure (101300 Pa), there is no change in height. Use the Bernoulli equation to calculate the velocity of the water exiting the nozzle.
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.
Losujemy ze zwracaniem trzy kule. Jakie jest pr- stwo, Že wylosujemy kule bialq? W pewnej populacji jest 20% blondynów. Do sali weszty 3 osoby. a) Jakie jest prawdopodobieñstwo, Že Žadna z nich nie jest blondynem? b) Dok\adnie jedna z nich jest blondynem? c) Przynajmniej jedna z nich jest blondynem?
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.
Exercise 1. The general form of a Bernoulli equation is dy dx +P(x)y = Q(x)yn, where P and Q are functions of x, and n is a constant. Show that the transformation to a new dependent variable z = y1−n reduces the equation to one that is linear in z (and hence solvable using the integrating factor method).
This document contains the answers to two practice problems applying the Bernoulli equation. The first problem calculates the velocity of water exiting a fire hose nozzle given the inlet velocity and pressures.
