Unreferenced date December 2009 In atmospheric dynamics and fluid dynamics , a hydrostatic fluid is a fluid in which fluid stresses act isotropic ally and fluid elements are in local equilibrium with one another. Thus, all directional fluid stresses, normally represented as vectors, can be summarized by a scalar physics scalar quantity called the hydrostatic pressure , which can still depend on position. The stress mechanics stress tensor takes on the form math sigma ij p delta ij math , where math p math is the hydrostatic pressure, and math delta ij math is the kronecker delta The equilibrium which exists in a hydrostatic fluid is often the result of a balance between forces that compress the fluid and forces that resist compression. For example, on earth, the atmosphere is compressed against the surface by gravity and supported by its internal energy . This is often referred to as hydrostatic equilibrium .

Unreferenced date March 2008 A hydrostatic skeleton or hydroskeleton is a structure found in many Poikilotherm cold blooded organisms and soft bodied animals consisting of a fluid filled cavity, the coelom , surrounded by muscles. The pressure of the fluid and action of the surrounding circular and longitudinal muscles are used to change an organism s shape and produce movement, such as burrowing or swimming. Some examples are soft bodied animals such as sea anemones and earthworms. Hydrostatic skeletons have a role in the locomotion of echinoderm s starfish, sea urchins , cnidarian s jellyfish , annelid s earthworm s , nematode s, and other invertebrate s. They have some similarities to muscular hydrostat s.

In continuum mechanics , a hydrostatic stress is an isotropic Stress mechanics stress that is given by the weight of water above a certain point. It is often used interchangeably with pressure and is also known as confining stress, particularly in the field geomechanics. Its magnitude math sigma h math can be given by math sigma h displaystyle sum i 1 n rho i g h i math where math i math is an index denoting each distinct layer of material above the point of interest, math rho i math is the density of each layer, math g math is the gravitational acceleration assumed constant here this can be substituted with any acceleration that is important in defining weight , and math h i math is the height or thickness of each given layer of material. For example, the magnitude of the hydrostatic stress felt at a point under ten meters of fresh water would be math sigma h,sand rho w g h w 1000 , text kg m 3 cdot 9.8 , text m s 2 cdot 10 , text m 9.8 cdot 10 4 kg ms 2 9.8 cdot 10 4 N m 2 math where the index math w math indicates water .

Image Hydroelectric dam.svg thumb As shown in this drawing, the hydrostatic head is the vertical distance between the water level in the reservoir and the turbine that is turned by the flowing water. When generating hydropower , the head is a general term used to describe the distance that a given water source has to fall before the point where power is generated. Ultimately the force responsible for hydropower is gravity , so a hydroelectric ity plant with a tall high head can produce more energy than a similar plant with a short low head. In short, a larger head allows water to fall a greater distance, which in turn allows more kinetic energy to accumulate. That energy is then harnessed by a water wheels water wheel or water turbines water turbine to create usable hydropower.

Unreferenced date September 2009 A hydrostatic test is a way in which leaks can be found in pressure vessels such as Pipeline transport pipelines and plumbing . The test involves placing water, which is often dyed for visibility, in the pipe or vessel at the required pressure to ensure that it will not leak or be damaged. It is the most common method employed for testing pipes and vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then continually re qualified at regular intervals using the proof pressure test which is also called the modified hydrostatic test . Hydrostatic testing is also a way in which a gas pressure vessel, such as a gas cylinder or a boiler , is checked for leak s or flaws. Testing is very important because such containers can explode if they fail when containing compressed gas. Testing procedures Hydrostatic tests are conducted under the constraints of either the industry s or the customer s specifications. The vessel is filled with a nearly incompressible liquid usually water or oil and examined for leaks or permanent changes in shape. Red or fluorescent dye s are usually added to the water to make leaks easier to see. The test pressure is always considerably higher than the operating pressure to give a margin for safety.

Electro hydrostatic actuators EHAs , are an emerging aerospace technology that aims at replacing Hydraulic cylinder hydraulic systems with self contained actuators operated solely by electrical power. EHAs would eliminate the need for separate hydraulic pumps and tubing, simplifying aircraft layout and improving safety and reliability. Conventional designs Aircraft were originally controlled by small aerodynamic surfaces operated by cables, attached to levers that magnified the pilot s mechanical advantage . As aircraft grew in size and performance, the aerodynamic forces on these surfaces grew to the point where it was no longer possible for the pilot to manually control them across a wide range of speeds controls with enough advantage to control the aircraft at high speed left the aircraft with significant overcontrol at lower speeds when the aerodynamic forces were reduced. Numerous aircraft in the early stages of World War II suffered from these problems, notably the Mitsubishi Zero and P 38 Lightning . Citation needed date August 2009 Starting in the 1940s, hydraulics were introduced to address these problems. In their early incarnations, hydraulic pumps attached to the engines would feed high pressure oil through tubes to the various control surfaces. Here, small valves were attached to the original control cables, controlling the flow of oil into an associated actuator connected to the control surface. One of the earliest fittings of a hydraulic boost system was to aileron s late war models of the P 38L, curing the need for great human strength in order to achieve a higher rate of roll. ref Lockheed P 38 Lightning Pilot s Flight Manual , pg. 5 ref Over time, the systems evolved to replace the mechanical linkages to the valves with electrical controls, producing the fly ..., http www.nasa.gov centers dryden pdf 88524main H 2210.pdf Performance of an Electro Hydrostatic ...

A Flow show is a device on a drilling rig petroleum drilling rig that is attached to the flow line and has a paddle that swings out as the flow of drilling fluid passes by it. The angle of the paddle increases as the volume of drilling fluid increases and pushes it out further and vice versa. The purpose of the flow show is to allow the driller and other rig personnel to monitor the flow of drilling fluid as it comes out of the hole. The reason for monitoring the flow If a high pressure zone is drilled and overcomes the hydrostatic pressure of the column of drilling fluid, the fluid or gas in the high pressure zone will begin to enter the borehole and increase the amount of fluid coming out of the hole. By monitoring the flow, rig personnel will know in advance before the flow becomes critical. If a low pressure zone is drilled and is overcome by the hydrostatic pressure of the column of drilling fluid, the low pressure zone may begin to take fluid and decrease the amount of fluid coming out of the hole. By monitoring the flow, rig personnel will know in advance before losing too much drilling fluid which is typically very expensive down the hole and or losing so much fluid that the hydrostatic pressure of the decreasing column of mud becomes so low that a blowout situation becomes imminent.

Orphan date October 2008 A jiggle syphon or siphon is the combination of a syphon pipe and a simple priming pump that uses mechanical shaking action to pump enough liquid up the pipe to reach the highest point, and thus start the syphoning action. Principle of operation The jiggle pump consists of a chamber, in line with the end of the pipe that sits in the liquid to be moved. The chamber is somewhat wider than the pipe, and narrows to approximately the pipe diameter at both ends. One end attaches to the pipe, the other end is open to the liquid. Within the chamber is a sphere, denser than the liquid to be pumped, small enough to move freely within the chamber but large enough to not be able to leave the chamber. ref http www.peakbusiness.co.uk canalpages liveaboard5.html Instructions for building a jiggle syphon ref To begin with, gravity holds the sphere at the bottom, open, end of the chamber, although hydrostatic pressure will force the liquid up and around the sphere upon immersion. When the pipe is vigorously shaken up and down, the sphere moves upwards, lifting some liquid in the pipe then when it falls down again, the increased hydrostatic pressure within the pipe which now has a higher hydrostatic head head of fluid in it than the surrounding container pushes the sphere down and prevents the liquid flowing back. Repeated jigglings lift the fluid up the pipe until it reaches the highest point in the pipe, whereupon gravity causes it to start to flow down the other side, and the syphon action will suck the liquid through the system. This causes the pressure in the pipe to drop below the hydrostatic pressure in the container, so the sphere is lifted upwards, allowing the liquid to flow. See also The Jiggle pump was first invented by the Chinese who used a similar system consisting of a small clay ball inside a hollow bamboo cane. With this devise they could pump water up to a small holding tank. Syphon for the principles and practice of syphoning. References r ... more details
