Investigation of the pressure variation in side flow systems through the Bernoulli principle

Abstract Specifically, we investigated the pressure variation that occurred in simple lateral flow systems through the Bernoulli principle. Such a fluid system is defined by an internal and external flow to a container of constant cross-sectional area through a hole located on its side. Flow may or may not be controlled to ensure constant acceleration in the system. We emphasize that we reproduce the referent system due to the action of the gravitational field. The results show that the knowledge of the fluid viscosity is essential in the interpretation of the system pressure variation.
