What is fluid mechanics?
The fluid mechanics are a physics industry concerning the study of fluids and the ways they interact with forces. Both liquids and gases are considered fluids for the purposes of this science. The field of fluid mechanics is often divided into two more specific study areas. It is the statics of fluids and dynamics of fluids that relate to fluids at rest and fluids in motion. The fluid mechanics may include very complex mathematics and the help of modern computers has significantly increased this science.
The chronological roots of the fluid mechanics will return to at least ancient Greeks. Greek physicist and inventor Archimedes was the author of some of the first studies we know about fluid statics, including buoyancy. In the medieval period of time, the Persian philosophers linked these ancient works with their own studies of fluid dynamics that acted as an early predecessor of modern fluid dynamics. Such well-ownership of historical characters like Leonardo da Vinci and Sir Isaac Newton, as well as another, contributedy to understand the mechanics of fluids.
Every type of science begins with the basic basic prerequisites that follow their studies. The fluid mechanics are usually defined as three basic spaces or prerequisites in its root. The first is to maintain the mass, which means that the weight cannot be spontaneously created or destroyed even if it can change the forms. The second assumption, maintaining momentum, is somewhat similar. This Act states that the total momentum in a closed system is constant and cannot spontaneously appear or disappears.
The third basic assumption of fluid mechanics is known as the hypothesis of continuum. This is a way to see fluids that do not take into account the presence of discrete molecules. Instead, it is expected that the properties of the fluid change continuously from one point to the other.
because it ignores the true nature of small particles of matter, the hypothesis of continuum is only approximation usedas a tool in calculations. This can lead to a slightly inaccurate solution, but also to a solution that is very accurate in ideal circumstances. There are other, more accurate methods, but this hypothesis is often quite useful as a preliminary assumption. Many times it can also be assumed that the fluid is incompressible, which means that it cannot be compressed. However, this only applies to liquids, not gases.
