5. The Bernoulli Equation - Loughborough University
learn.lboro.ac.ukBernoulli’s equation is one of the most important/useful equations in fluid mechanics. It may be written, p g u g z p g u g 11 z 2 1 22 2 ρρ222 ++=++ We see that from applying equal pressure or zero velocities we get the two equations from the section above. They are both just special cases of Bernoulli’s equation.

Figure 4-4. - cu.edu.tr
abs.cu.edu.trAssumptions: 1) The flow exiting into the air is steady, incompressible, and irrotational (so that the Bernoulli equation is applicable). 2) The water pressure in the hose near the outlet is equal to the water main pressure. 3) The surface tension effects are negligible. 4) The friction between the water and air is negligible.
Bernoulli Equation Practice Worksheet Answers
www.teachengineering.orgBernoulli 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.
