1. Fluid mechanics
Fluid mechanics is related to the fluids that are in motion and forces acting on them. Fluid mechanics has two branches fluid statics and fluid dynamics. In Fluid Mechanics we actually observe fluid motion and calculation of the effect of forces on motion of fluid. It is category of continuum mechanics in which we study models matter without using the information about atomic structure. FM is an active area of research with many problems left to be solved. 1.1 Main …show more content…
Water is an example of it because it continues to display its properties no matter how much it is stirred or mixed. A slightly less rigorous definition is that the drag of a small object being moved slowly through the fluid is proportional to the force applied to the object. Important fluids, like water as well as most gases, behave as a Newtonian fluid under normal conditions on Earth.
On the opposite side, stirring of a non-Newtonian fluid can leave a "hole" in the liquid. This will gradually fill up over time – this behavior is present in materials such as oobleck, pudding, or sand (although sand isn't strictly a fluid). Alternatively, stirring a non-Newtonian fluid can cause the viscosity to decrease, so the fluid gets "thinner" (this is present in non-drip paints). There are many types of non-Newtonian fluids, as they are defined to be something that fails to obey a specific (particular) property i.e., most fluids with long molecular chains can react in a non-Newtonian way. The constant of proportionality between the velocity gradient and the viscous stress tensor is known as the …show more content…
As we know that, on earth, the major part of water is saltwater so desalination systems have become a practical means of increasing freshwater supplies. Desalination is mostly useful in locations that lack necessary groundwater or rainfall but it can also supplement existing resources. There are some drawbacks of desalination. The marine ecosystem can get damaged as the highly concentrated brine that is ejected to the ocean. One way to lessen this threat is to dilute the brine with a waste water
