INTRODUCTION: BASIC EQUATION IN FLUID MECHANICS


Derivations of the basic equations of fluid mechanics are very necessary because they fulfill the requirements for the broadest applicability in areas of science and engineering. Fluid mechanics considerations are applied in many fields, especially in engineering. Concerning the formulation of the basic equations of fluids mechanics, it is easy to formulate the conservation equations for mass, momentum, energy and chemical species for a fluid element. The derivations of basic equations can be represented in an easily comprehensible way and it is possible to build up the derivations upon the basic knowledge of physics. Derivations of the basic equations are usually followed by transformation considerations whose aim is to derive local formulations of the conservation equations and to introduce field quantities into the mathematical representations.

            The objective of the derivations is to formulate the conservation laws for mass, momentum, energy and chemical species in such a way that they can be applied to all the flow problems that occur. Common equations in fluid mechanics are Bernoulli equation. The equation is a statement of the conservation of energy in a form useful for solving problems involving fluids. For non-viscous, incompressible fluid in steady flow, the sum of pressure, potential and kinetic energies per unit volume is constant at any point. Then, the common equation that used in fluid mechanics are Navier-Stokes equations which are the motion of a non- turbulent, Newtonian fluid is governed by that equation. The equation can be used to model turbulent flow, where the fluid parameters are interpreted as time-averaged values.in that case,  there are so many equations that have been derived to make a formula which can make life easier in doing everyday works.
