The tube is filled with liquid and is inserted in a jar also containing same liquid.The liquid initially drops in tube due to gravity but stabilizes at certain level under the action of atmospheric forces.The atmospheric pressure is then measured as height of liquid at which it stabilizes. The property pressureis discussed in Chap. 3 together with fluid statics. 35 CHAPTER2 OBJECTIVES When you finish reading this chapter, you should be able to Have a working knowledge of the basic properties of fluids and understand the continuum approximation Have a working knowledge of viscosity and the consequences of the frictional effects it causes in fluid flow Calculate the capillary Properties of Fluids MCQ Question 3: A cylindrical shaft of diameter 'D' rotates about a vertical axis inside a fixed cylindrical tube of length 'L' and a very thin gap of 'h' between shaft and tube.

The density of a fluid is defined as the ratio of the mass of the fluid to its volume. The density of gases is dependent on pressure and temperature, while the density of liquid remains constant. The density of water is 1000 kg.m -3 while density of air is 1.225 kg.m -3. ρ = m a s s o f u i d v o l u m e o f u i d.

Specific Weigh Clarification: A fluid in static condition has no shear stress. The shear stress is known as force per unit area that is acting parallel to the inconsiderable surface element. It is mainly caused by the friction between fluid molecules due to viscosity of the fluid. 10. What causes the turbulence in fluid flow? a) Kinetic energy b) Pressure Fluid Statics When the fluid velocity is zero, called the hydrostatic condition, the pressure variation is due only to the weight of the fluid. Consider a small wedge of fluid at rest of size Δx, Δz, Δs and depth b into the paper. There is no shear stress by definition, and pressure is assumed to be identical on each face (small element). Part of the Fluid Mechanics and Its Applications book series (FMIA,volume 86) Abstract Fluid statics is the part of fluid mechanics that deals with fluids when there is no relative motion between the fluid particles. Typically this includes two situations: when the fluid is at rest and when it moves like a rigid solid. fluid mechanics - .syllabus for fluid mechanics . fluid properties; fluid statics, manometry, Fluid. A fluid is a substance, such as liquid or gas that has no rigidity like solids. Liquids are distinguished from gases by the presence of a surface. As fluids have no rigidity, they fail to support a shear stress. When a fluid is subjected to a shear stress, the layers of the fluid slide relative to each other.
