WebBernoulli’s equation in that case is p 1 + ρ g h 1 = p 2 + ρ g h 2. We can further simplify the equation by setting h 2 = 0. (Any height can be chosen for a reference height of zero, as is often done for other situations involving gravitational force, making all other heights relative.) In this case, we get p 2 = p 1 + ρ g h 1. Web5.2 Bernoulli’s Equation Bernoulli’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.
