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.

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 ...

It was directed and produced by twin brothers Wolfgang Lauenstein Wolfgang and Christoph Lauenstein . The film depicts five individuals living on a small platform floating in space. Whenever one of them moves, the others must do so as well to ensure that the platform does not tip over. The group works cooperatively to maintain a balance until one individual pulls a box onto the platform. Since all are curious as to what the box is, the individuals try to inspect the box and their actions disrupt the balance of the platform, and those on it. All but one of the individuals is pushed or falls off the edges of the platform. In the end, the lone individual must maintain a balance with the box, which is well out of reach. Balance won the Academy Award for Animated Short Film Academy Award for Best Animated Short of 1989.

Most countries do not have a zero visible balance they usually run a surplus or a deficit. This will be offset by trade in services, other income transfers, investments and monetary flows, leading to an overall balance of payments . The visible balance is affected by changes in the volumes of imports and exports , and also by changes in the terms of trade . In aggregate, the World often appears to have a negative visible balance with itself i.e. imports of goods appear to exceed exports.

Multiple issues orphan February 2009 unreferenced January 2009 cleanup January 2009 context January 2009 Video camera s also have a function known as black balance , just like they have a white balance which gives reference to true white to the CCD s. Unlike Color temperature white balance , black balance is not adjusted every time. Purpose Its main purpose is to eliminate any residual current being output from the pixel sites under conditions of complete darkness, often referred to as Johnson Nyquist noise thermal noise . That s why the camera will automatically close the iris completely when it does the black balance. Conditions under which you may want to black balance are typically when the camera experiences a large change in operating temperature , especially from colder to warmer. Otherwise, it is a periodic thing to allow for other minor factors that could come into play. With CMOS sensor technology, black balancing may not be as necessary as it is with CCD type devices. We all talk about how clean and relatively noise free CMOS sensors are by design Availability Black balancing is done only in professional cameras. Amateur handycam users need not worry about black balance. Professional camcorders like the Sony DSR 400, Panasonic DV DVC Pro etc. have a switch which has to be flicked upwards to do the white balance. The same switch when pressed downwards does a black balance. In the Panasonic 102 3ccd series, the white balance switch when pressed just once triggers white balancing and when depressed and held for a few seconds completes the black balance. Most cameramen never touch the black balance. You can do the black balance if you feel that the colours are not truly represented even after doing the white balance. Frequency of black balance adjustment There is a lot of debate on whether it is necessary to do the black balance every time. Panasonic 102 XB camera operating instructions manual suggests that you black balance when You use the camera for the fi ... more details
