<div class = "text-justify"> If we take into account that the mechanics of a fluid deals with the study of fluids in movement, associating these two words we can call it dynamic fluid, and if we study it in static conditions, that is to say fluid at rest, both liquid and gases are considered fluid, and the number of applications of fluid mechanics is enormous, although my publication refers to the importance of the study of the mechanics of a fluid in engineering, in the field of medicine, we find various applications on various body functions such as breathing, blood flow among others, for other branches of engineering we can name: designs of fans, turbines, airplanes, ships, windmills, engines, filters , jets and sprinklers, we could say that almost all the things we see and use on our planet are fluid or move close to a fluid.

If the analysis and studies of fluids do it in the field of science, we could focus their study and understanding within the field of theory and experimentation, if we take into account that the mechanics of a fluid has a set of laws that they govern the behavior of conservation and the balance of matter, we would be talking about a rigorous source of theoretical documentation where a rigorous theoretical treatment is needed, however, the theory is sometimes frustrating, because it refers mainly to certain idealized situations that can be invalid in practical cases. There is a wide variety of difficulties that have to overcome the fluids, is the geometry and viscosity the two major obstacles for the treatment are geometry and viscosity.

Most of the study of fluids takes place under geometric configurations, whose structure are flat plates, circular conduits and other simple geometries, although with the advance of computational fluid mechanics has made that they can already study and apply numerical methods to bodies arbitrary geometries that contain liquid or gaseous fluids.

The theory also has to address as an obstacle to viscosity, taking into account that this is not more than the resistance of a fluid to be able to flow, where its behavior can only be neglected in fluids that are studied as ideal fluids, another impediment for the study of fluid mechanics is the fact that the viscosity increases the difficulty of the basic equations, the viscosity also affects the stability of the fluids in their transport resulting in a great phenomenon of study as is the case of the *** turbulence ***.

# Theoretical and experimental field of fluids

There are several theories to study the flow of fluids, in turn the validity of these theories must have an experimental support, the experimentation provides a natural and simple complement to the theory, taking into account that theory and experimentation go hand in hand in all fluid mechanics studies.

***In particular I can mention that anyone who begins to study and understand the way in which fluids (liquids and gas) behave in their two conditions, dynamic and static, can be sure that in their study, in the university for his undergraduate or postgraduate studies, he will have the theoretical foundations that his professors give him through the diversity of existing texts, but in parallel he will always need that theoretical study is sustained with something more than theory, For this purpose, the fluid mechanics laboratories should be in place, in which tank filling and emptying practices can be carried out by means of pipes, with accessories such as valves, pressure gauges, turbines, pumps, compressors and heat exchangers. heat, where each and every one of the theories is supported by laboratory practices. Once started in the labor field and putting into practice each and every one of our knowledge in fluid mechanics we can continue supporting all the theories that govern the behavior of the fluids already in the direct application of real cases, in my case in particular I noticed that when working as an Operations Engineer in the oil industry, all the drilling activities needed a continuous and closed supervision especially in the drilling fluid path, especially in the supervision of the properties that he had to maintain during all his travel, since they left the mud tanks pumped by mud pumps, to enter the well and return again to meet its cycle, are properties such as density, viscosity, rheology among others that contracted with the ideal conditions that taught me in the university, is a very different behavior and at different levels, the one shown by these fluids in The field that is under ideal conditions of pressure and temperature, than those found in most cases at depths of 7000, 8000, 9000 up to 18000 feet deep.***

***The relevant reflection of this article is that in the diversity of science and engineering technology, a wide variety of fluids are used, from the most common, such as water, to the most complex, such as oils, emulsions, among others. , that its study and understanding are of vital importance for the advancement and development of Engineering: civil, oil, mechanical, industrial, food among others.***</div>
