While a dimension expresses a specific type of physical quantity, a unit assigns a number so that the dimension can be measured. Because of the continuum assumption, fluid parameters such as density and velocity can be considered continuous functions of position with a value at each point in space. Recall that a limit concept, for example, involves letting a length, an area, or a volume approach zero.

When the continuum assumption is valid, engineers can apply limit concepts from differential calculus. This idea is called the continuum assumption. That is, a fluid often behaves as if it were comprised of continuous matter that is infinitely divisible into smaller and smaller parts. While a body of fluid is comprised of molecules, most characteristics of fluids are due to average molecular behavior. Both liquids and gases are classified as fluids.ДЇLUID MECHANICS IES MASTER GATE MATERIAL : CLICK HERE Alternatively, a solid will deform under the action of a shear stress but will not flow like a fluid. More specifically, a fluid is a substance that will continuously deform-that is, flow under the action of a shear stress. In contrast to a solid, a fluid is a substance whose molecules move freely past each other. When the material body is in the gas or liquid phase, the discipline is called fluid mechanics. When mechanics applies to material bodies in the solid phase, the discipline is called solid mechanics. Mechanics involves force, energy, motion, deformation, and material properties. Mechanics is the field of science focused on the motion of material bodies. Control Volume Approach and Continuity Equation.Applications and Connections of Fluid Mechanics.
