Fluid mechanics, science concerned with the response of fluids to forces exerted upon them. Density density, as you will see, is an important characteristic of substances. Hydrostatic pressure distribution pressure in a continuously distributed uniform static fluid varies only with vertical distance and is independent of the shape of the container. Fluid mechanics is concerned with the behavior of materials which deform without limit under the in. Suppose that a cube of mass m 0 is submerged in a fluid this time, the cube is an external object, not a cube of water. Pressure in the spinal fluid is measured as shown in figure. In a moving fluid there will be both static and dynamic pressure definitions.
Fluids and elasticity in this chapter we study macroscopic systems. It is important that you keep up with and complete the athomeoutofclass video assignments because we will be addressing these topics in class the next day. Learn more about pressure, buoyant force, and flowing fluid so you can appreciate the sometimes invisible, but crucial, effect they have on us and the world around us. It is crucial, for example, in determining whether an object sinks or floats. Summary the goal of chapter has been to understand the static and dynamic properties of fluids. Indeed, the idea of exploiting the laws of ideal fluid mechanics to.
We shall discover later that the situation is rather different when the dynamic forces of a moving fluid stream are considered section 2. Fluid statics study material for iit jee askiitians. Find and study its derivation in your fluid mechanics book. This pressure is transmitted to a second piston of radius of 6. Steady flow stream line flow it is the flow in which the velocity of fluid particles crossing a particular point is the same at all the times. Different properties are discussed, such as density and pressure. For this reason it is possible to study the statics of solids by characterizing them as rigid bodies. Pressure and fluid statics pressure for a static fluid, the only stress is the normal stress since by definition a fluid subjected to a shear stress must deform and undergo motion. You probably think of a fluid as a liquid, but a fluid is simply anything that can flow. Fluid dynamics and statics and bernoullis equation overview. Explain the physical characteristics of solids, liquids, and gases. Hence, static pressure is a scalar rather than a vector quantity.
