    858 Words  | 4 Pages

    Fluid statics or what others call hydrostatics is the branch of fluid mechanics that studies incompressible fluids at rest. It encompasses and includes the study of the conditions under which fluids are at rest in stable equilibrium as opposed to fluid dynamics which is the study of fluids in motion. Hydrostatics are categorized as a part of the fluid statics, which is the study of all fluids, incompressible or not, at rest. In addition, Fluid Statics and Fluid Dynamics form the two constituents

In retrospection, the majority of Earth is covered with a fluid (water), and is inhabited by living organisms that are mainly composed of water. With these statistics in mind, how could fluids not have a significant influence on the world around us? The study of fluids and their behaviors is defined as fluid dynamics. Fluid dynamics is concerned with the flow of liquids and gases, usually in or around solid surfaces. Applications of fluid dynamics

Limp frame porous media : It is similar to the rigid frame assumption, but removed framed dynamics. Elastic frame porous media : It is more valid as it includes the frame motion. It turns out that three waves exist in a Poro-elastic material. (M.R.F. Kidner) Many researchers have studied the porous media in order to predict the characteristics

  • Aerofoils Case Study

    1891 Words  | 8 Pages

    2.3 Aerofoil Aerofoil is the cross-sectional of an object that are moved through a fluid such as air, and aerodynamics force created. Aerofoils are employed on aircraft as wings so then it will produce lift or others depending to the blade shape to produce thrust. The two of these forces are perpendicular to the air flow. Drag is a consequence of the production of lift/thrust and acts parallel to the airflow. Other aerofoil surface includes tail-planes, fins, winglets, and helicopter rotor blades

    Background and History Archimedes’ Principle Archimedes’ Principle saied that when a body immersed in a liquid it will has an upward force equal to the weight of fluid displaced. In order to float, the volume of the vessel below the water it will displace a weight of liquid equal to the total weight of the vessel. The upward force produced by the displacement of water is termed buoyancy or displacement, and is given the symbol ‘FB’ in Figure below. Bernoulli Principle The term hydrodynamics

  • Essay On Fluid Permeability

    851 Words  | 4 Pages

    material is called a ‘fluid’. Fluid mechanics is that branch of science which deals with the behavior of the fluids (liquids or gases) at rest as well as in motion. Thus, this branch of science deals with the static, kinematics and dynamic aspects of fluids. The study of fluids at rest is called fluid statics. The study of fluids in motion, where pressure forces are not considered, is called fluid kinematics and if the pressure forces is also considered for the fluids in motion, that branch

    lift, drag, and weight. In 350 B.C., Aristotle devised the idea that air has weight and he examined that an object moving through a fluid experiences resistance, or drag. Drag is the force of air opposition propelling in the reverse direction of an aircraft. One hundred years later in 250 B.C., Archimedes observed that the pressure of an object that is immersed in a fluid, in either gas or liquid form, is proportional
