Oil flows through a contraction with circular cross-section as shown in the figure below. A manometer, using mercury as the gage fluid, is used to measure the pressure difference between sections 1 and 2 of the pipe. Assuming frictionless flow, determine: the pressure difference, p1-p2, between sections 1 and 2, and.
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 ...
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.

20 lip 2022 · We begin by applying Bernoulli’s Equation to the flow from the water tower at point 1, to where the water just enters the house at point 2. Bernoulli’s equation (Equation (28.4.8)) tells us that \[P_{1}+\rho g y_{1}+\frac{1}{2} \rho v_{1}^{2}=P_{2}+\rho g y_{2}+\frac{1}{2} \rho v_{2}^{2} \nonumber \]
20 cze 2020 · In this article exercises with solutions based on the Bernoulli equation are given. Bernoulli equation. The Bernoulli equation is based on the conservation of energy of flowing fluids. The derivation of this equation was shown in detail in the article Derivation of the Bernoulli equation. For inviscid and incompressible fluids such as liquids ...
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.
