# Topic: Fluid statics

###### In the News (Mon 15 Jul 19)

 Fluid statics - Definition, explanation Fluids are characterised by their inability to sustain a shear stress in equilibrium. A fluid, then, can only exert stress normal to any contact surface, and the accompanying pressure in the fluid is the same in all directions for a static fluid. Density, ρ, of a fluid is, in general, a function of temperature and, in the case of compressible fluids, of pressure. www.calsky.com /lexikon/en/txt/f/fl/fluid_statics.php   (681 words)

 Fluid Mechanics - MSN Encarta Fluid Mechanics, physical science dealing with the action of fluids at rest or in motion, and with engineering applications and devices using fluids. Fluid mechanics can be subdivided into two major areas: fluid statics, or hydrostatics, which deals with fluids at rest, and fluid dynamics, concerned with fluids in motion. The second important principle of fluid statics was discovered by the Greek mathematician and philosopher Archimedes. uk.encarta.msn.com /encyclopedia_761578780/Fluid_Mechanics.html   (1400 words)

 Fluid Mechanics - Search View - MSN Encarta It follows that the force per unit area, the pressure, exerted by the fluid against the walls of an arbitrarily shaped containing vessel is perpendicular to the walls at every point. Known as Pascal's law, it states that the pressure applied to an enclosed fluid is transmitted equally in all directions and to all parts of the enclosing vessel, if pressure differences due to the weight of the fluid can be neglected. This branch of fluid mechanics deals with the laws of fluids in motion; these laws are considerably more complex and, in spite of the greater practical importance of fluid dynamics, only a few basic ideas can be discussed here. uk.encarta.msn.com /text_761578780__1/Fluid_Mechanics.html   (2613 words)

 Fluid pressure Summary Open conditions are considered to be "static" or not moving (even in the ocean where there are waves and currents) because the fluid is essentially "at rest." The pressure in open conditions conform with principles of fluid statics. The concepts of fluid pressure are predominantly attributed to the discoveries of Blaise Pascal and Daniel Bernoulli. In the case where the fluid is at rest, called fluid statics or hydrostatics (from hydro meaning "water" and static meaning "at rest"), the force acting on the object is the sheer weight of the fluid above, up to the water's surfaceâ€”such as from a water tower. www.bookrags.com /Fluid_pressure   (1692 words)

 Fluid statics Fluid statics (also called hydrostatics) is the science of fluids at rest, and is a sub-field within fluid mechanics. The use of fluid to do work is called hydraulics, and the science of fluids in motion is fluid dynamics. This characteristic allows fluids to transmit force through the length of pipes or tubes, i.e., a force applied to a fluid in a pipe is transmitted, via the fluid, to the other end of the pipe. www.dejavu.org /cgi-bin/get.cgi?ver=93&url=http%3A%2F%2Farticles.gourt.com%2F%3Farticle%3Dhydrostatics%26type%3Den   (695 words)

 Fluid Mechanics Fluid mechanics is the study of such materials and includes those materials that we intuitively regard as liquids and gasses. Of course the behavior of fluids is determined by the behavior of the particles that make them up, but we will in general not pry into the private lives of individual particle, just consider how the whole society of particles behaves in fluids. The pressure exerted by a fluid at a particular depth, h, is defined as the force per unit area that the fluid exerts on an object submerged to that depth. www.mcasco.com /p1fluidmech.html   (3727 words)

 Fluid - Engineering - A Wikia wiki Fluids share the properties of not resisting deformation and the ability to flow (also described as their ability to take on the shape of their containers). The behaviour of fluids is described by a set of partial differential equations [[8]], including the Navier-Stokes equations [[9]]. The study of fluids is fluid mechanics which is then subdivided into fluid dynamics and fluid statics depending on whether the fluid is in motion or not. engineering.wikia.com /wiki/Fluid   (317 words)

 Dictionary : Fluid_Mechanics Fluid mechanics is one of the oldest and broadest fields of engineering. Branches of fluid dynamics include hydrodynamics (study of liquids in motion) and aerodynamics (study of gases in motion) as well as vortex dynamics, gas dynamics, computational fluid dynamics (CFD), convection heat transfer, flows of turbo machinery, acoustics, bio-fluids, physical oceanography, atmospheric dynamics, wind engineering, and the dynamics of two-phase flows. Then, the fluid flow physics is applied to this virtual model, and the software generates a prediction of the flow about or inside the body being studied. www.centennialofflight.gov /essay/Dictionary/Fluid_Dynamics/DI116.htm   (337 words)

 Aerodynamics for Students   (Site not responding. Last check: 2007-10-27) Hence, for a moving fluid pressure is defined as an average of the three normal stresses acting upon the fluid element. Density is constant for incompressible fluids and varies with pressure and temperature for compressible fluids. One of the direct applications of the equation of Fluid Statics we have derived is in the devices used to measure pressure. www.ae.su.oz.au /aero/fprops/statics/node2.html   (2833 words)

 ME 111 Topic 3 Fluid statics involves a special class of problems in fluid mechanics, where the fluid is not flowing. When the velocity of the fluid is zero everywhere, Newton’s law of viscosity shows that there are no shear forces in the fluid, since zero velocities imply zero velocity gradients in all directions. Thus, the only forces, which play a role in fluid statics, are pressure forces. www.engr.sjsu.edu /nikos/courses/me111/statics.htm   (329 words)

 Fluid pressure - Wikipedia, the free encyclopedia Fluid pressure is the pressure at some point within a fluid, such as water or air. Pressure in open conditions usually can be approximated as the pressure in "static" or non-moving conditions (even in the ocean where there are waves and currents), because the motions create only negligible changes in the pressure. The pressure in closed conditions conform with the principles of fluid dynamics. en.wikipedia.org /wiki/Fluid_pressure   (195 words)

 Static Equations in Fluid Mechanics A barotropic, compressible fluid at rest is governed by the statics equation, For an incompressible fluid, the statics equation simplifies to, If the fluid is compressible but barotropic, then the density and the pressure can be integrated into the "pressure per density" function www.efunda.com /formulae/fluids/fluid_statics.cfm   (176 words)

 Conservation of Mass In the center of the figure, we consider an amount of a static fluid, liquid or gas. If we change the fluid from some state "a" to another state "b" and allow it to come to rest, we find that, unlike a solid, a fluid may change its shape. As the speed of the flow approaches the speed of sound the density of the flow is no longer a constant and we must then use a compressible form of the mass flow rate equation. www.grc.nasa.gov /WWW/K-12/airplane/mass.html   (655 words)

 Fluid Statics Pressure is everywhere the same at the same depth (as long as the fluid is static). If the fluid is moving there can be changes of pressure along a given horizon. It includes the pressure from the atmosphere (air pressure), the pressure from any external forces applied to the fluid and the pressure resultant from the weight of the fluid itself. www.cet.nau.edu /Projects/WDP/resources/Hydraulics/FluidStatics.htm   (2196 words)

 Fluid Statics The fact that there is greater pressure at lower depths in a fluid than close to the surface explains why there is an upward force (called buoyant force) on any submerged object. For example: I might tell you that the fluid is seawater or blood rather than water, so you should use the appropriate fluid density to calculate gauge pressure and/or buoyant force. forgetting that the buoyant force on a totally-submerged object does not depend on the depth of fluid, or on what other forces might be acting on the object (such as normal force). www.sage.edu /faculty/vozzof/genphys/fluid.html   (726 words)
