FLUID MECHANICS

Fluid mechanics is the study of fluids and the forces on them. (Fluids include liquids, gases, and plasmas.) Fluid mechanics can be divided into fluid statics, the study of fluids at rest; fluid kinematics, the study of fluids in motion; and fluid dynamics, the study of the effect of forces on fluid motion. It is a branch of continum mechanics, a subject which models matter without using the information that it is made out of atoms, that is, it models matter from a macroscopic viewpoint rather than from a microscopic viewpoint. Fluid mechanics, especially fluid dynamics, is an active field of research with many unsolved or partly solved problems.

 ASPECTS OF THE FLUID MECHANICS

THE SIZE: For flow of fluid within pipes, the pipe diameter is a characteristic length.

SPEED: The speed of an object is the magnitude of its velocity (the rate of change of its position); it is a scalar quantity.

PRESSURE: Pressure (the symbol: p) is the force per unit area applied in a direction perpendicular to the surface of an object.

HISTORY OF FLUID MECHANICS

This discipline was born with the emergence of agriculture in the early civilizations, which involved the creation of irrigation systems and canals and the accumulation of the first body of knowledge on water and would enhance a boom in shipping.

• Archimides: Great Roman waterworks.
• Leonardo Da Vinci: Turn to rethink the study of streams.
• Toricelli and Pascal: Explosion primitive Fluid Mechanics.
• Newton: Laws of the dynamics of fluids which subsequently broaden Bernoulli, Euler, Lagrange, Cauchy and the rest of the great minds of classicla mechanics.
• Navier-Stokes: tensor calculus and the Navier-Stokes equations, let us establish the traditional hydraulic problems: pipes, channels, etc,
• Reynolds: He analyzed the turbulent flow and got the number that bears his name, laying most of the conventions in this field. Meanwhile, broke throughdimensional analysis, which would emphasize Rayleigh, froude and others.
• Doppler, Rayleigh and Mach: Analysis of the gases and sunds.
