Definition 1. The Bernoulli differential equation is an equation of the form y0+ p(t)y= q(t)yr, where r6= 0 ,1 is a real number. In the exclusive cases r= 0,1 the above equation is a linear equation of the 1st order (homogeneous for r = 1, non-homogeneous for r = 0), and thus is easy to solve. In all the other cases, the
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.
