We have seen that the law above is of fundamental importance in the analysis of fluid mechanics. In it, the following parameters appear:
- Geodetic contribution of the trio Bernoulli
- kinetic contribution of the trio Bernoulli
- pressure contribution of the trio Bernoulli
- contribution attributable to the pressure drop
The Bernoulli trinomial tends to preserve it in the different sections taken into account, considering the motion of an ideal fluid. Well, we live in a real world, where often the ideality approximation can not be applied. In the motion of a real fluid there is a further contribution in the equation: the dissipative effect, quantified by the load losses. This is related to viscous forces, which create phenomena of friction.
