The scope of the production processes is extremely varied. It is also true that most of the productions are united by a necessity: the fluid handling. In fact, if in the process it is necessary the use of liquid or gaseous currents, must be introduced appropriate devices that allows the movement of these currents.
In the case of interest to us, namely the treatment of gaseous pollutants, equipment that allow the handling of gaseous currents are fans and industrial ventilation systems.
The objective of this article is to provide information about the physical laws that underlie the fluid handling and, therefore, the operation of the fans. In particular, we will analyze:
- The conservation of mass
- The energy conservation law
- A practical example, to see how these laws govern the motion of a gaseous flow inside a pipe
