A Complete Guide to Fluid Mechanics Fundamentals and Applications

In this section, we introduced the physical properties of fluids, the distinction between laminar and turbulent flows, and the forces that are known as buoyancy, drag, and lift. Mechanical engineers categorize substances as being either solids or fluids, and the distinction between the two centers around how they respond to a shear stress. You’ll find details about Lift and Drag forces in these links –

You will find All the important topics of the basic fluid mechanics which are enclosed in the links of this guide to fluid mechanics fundamentals and applications .  

Although a solid material will deform by only a small amount and resist shear stress by virtue of its stiffness, a fluid will respond by flowing in a continuous steady motion.Mechanical engineers apply the principles of fluid engineering to applications such as aerodynamics, biomedical engineering, microfluidics, and sports engineering. The flow of fluids through pipes, hoses, and ducts is an example of this diversity.

In addition to the distribution of water, gasoline, natural gas, and air through piping systems, the principles behind fluid flow in pipes can be applied in studies of the human circulatory and respiratory systems. The primary variables, symbols, and conventional units that are used in this chapter are summarized in Table 6.5, and the key equations are listed in Table 6.6 (see below).

The buoyancy force develops when an object is immersed in a fluid, and it is related to the weight of the displaced fluid. Drag and lift forces develop when there is relative motion between a fluid and a solid object, and they encompass situations where the fluid is stationary and the object is moving (as in the case of an automobile); the fluid is moving and the object is stationary (as in wind loading on a building); or some combination of the two. The magnitudes of drag and lift forces are generally calculated in terms of drag and lift coefficients, which are numerical quantities that capture the complex dependency of these forces on an object’s shape and its orientation relative to the flowing fluid.

Basic Mechanical Engineering is a small endeavor for the mechanical engineering students and fresh graduates. All the articles are written by mechanical "rocking" engineers \m/
