Hot water is much less dense than cold water and this is used in the displacement principal on which most storage water heaters operate. If cold water is fed into the bottom of a tank full of hot water it will displace an equal quantity of hot water out of the top of the tank, and if the heater is correctly designed the hot water will float on the cold water for a considerable time without mixing. All Dux storage water heaters in current production use the displacement principal.
The weight of water (in long tons) displaced by a vessel afloat at the draft under consideration. "Light displacement" is the displacement when the vessel is unloaded of cargo, stores, potable water, and most of the fuel. "Loaded displacement" is the displacement when the vessel is fully loaded with cargo, fuel, water, stores, etc.
A measure of an engine's total volume. It's the difference between the volume contained in the cylinders when the pistons are at the bottom of the stroke and the volume that remains when the pistons are at the top of the stroke. It can be calculated using the formula:( bore stroke)x(0.785)x(n), where "n" = the number of cylinders.
The displacement of an engine is the total volume displaced by one piston when it moved fro bottom dead center to top dead center multiplied by the number of cylinders (measured in cubic inches or liters).
Displacement, or "swept" volume, is the measured volume travelled by the piston as it travels from it's lowest point to highest point in a stroke. It can be expressed as any cubic measurement but is usually referred to as CC's (cubic centimeters) or Liters (1000 cc = 1 liter) or sometimes, in cubic inches, although that practice is slowly dying out.
A measure of an engine's size. It's the difference between the volume contained in the cylinders when the pistons are at the bottom of the stroke and the volume that remains when the pistons are at the top of the stroke. It can be calculated by multiplying bore times stroke times 0.785 times the number of cylinders.
Meaningful only in positive displacement compressors, the entire volume that is swept by the repetitive motion of the pumping element. Displacement per revolution depends on the size of the pumping chamber or chambers, and displacement per minute is determined by compressor speeds.
Archimedes jumped out of the bath to say “A floating body displaces its own weight of water”. So the displacement of a boat is just its weight, but you can also use the word to describe the volume of the boat under the water. Because 1 gram of fresh water has a volume of 1 cubic centimetre, a boat weighing 2000 grams (2 kilograms) will need to displace 2000 cubic centimetres (2 litres) of water to let it float. So you need to design the boat with that volume under water. (Boats float higher in sea water – think about why!)
The size of the engine; specifically, the total volume found in the cylinders. This is usually expressed in cc (cubic centimeters) or ci (cubic inches). Generally, the larger the displacement, the more powerful the motor.
In an engine, the total volume of air or air-fuel mixture an engine is theoretically capable of drawing into all cylinders during one operating cycle. Generally expressed in liters or cubic inches. Engine displacement is equal to (bore) x (bore) x (stroke) x (number of pistons) x (.785). Distributor A component of the ignition system, usually driven by the camshaft that directs high-voltage surges to the spark plugs in the proper sequence.
The weight of a boat measured as a the weight of the amount of water it displaces. A boat displaces an amount of water equal to the weight of the boat, so the boat’s displacement and weight are identical.
Sum of the volumes swept by an engine's pistons as they travel up and down in their cylinders. Based upon bore (diameter of cylinder) and stroke (distance traveled by piston). Expressed in liters or cubic inches.
The displacement of an engine, usually given in either cubic inches or liters, is a measure of the volume of its cylinders. How much air they can draw in is a theoretical gauge to both size and power output.
Refers to the volume of space a piston displaces, and implies an engine’s ability to produce thrust. It may be measured in cubic inches (cu. in) or cubic centimeters (cc), although neither unit may appear. The most popular displacement range in the U.S.A. is .40-size (that is, engines with a displacement of around 0.40 cu. in). However, displacements can range from as little as .049 (for 1/2A kits) up to 7.32 cu. in. for some gas engines.
In an engine, the total volume of air-fuel mixture an engine theoretically is capable of drawing into all cylinders during one operating cycle. Usually expressed in cubic inches (e.g. 358 cu.in.) or liters (e.g. 4.2 liter).
The measurement of cubic volume that an item (such as a speaker or port) takes away from the internal volume of an enclosure. When designing an enclosure, this figure must be added to the enclosure volume.
A Freudian term designating the process, or result, of redirecting an emotion or impulse from its original object to a more acceptable one. When a child who is angry at a friend expresses hostility toward a sibling, the anger is displaced. Displacement has been invoked along with condensation by psychoanalytically oriented semioticians and others to illuminate the way language works.
a) A defense mechanism whereby a motive that may not be directly expressed (such as sex or aggression) appears in a more acceptable form. See also defense mechanism. b) The principle of loss of items from short-term memory as too many new items are added. See also chunk, short-term memory.
In Freudian theory, the psychological process of defending oneself from awareness of painful stimuli by transferring or projecting them into another form, perceived to be safer, and less volatile. In mythology, demonized characters such as ogres, temptresses, devils, and so forth symbolically embody--through displacement--aspects of the Self that are too volatile to be accepted directly. Scapegoating is the ultimate expression of displacement. Ostensibly a defense of the hero's safety, this process actually creates obstacles that the hero must ultimately overcome if he is to arrive at full atonement, i.e., acceptance of the Other as integral to the Self.
according to Freudian in psychoanalytic theory, displacement is when a person shifts his/her impulses from an unacceptable target to a more acceptable or less threatening target. For example, if you are very angry at your teacher because you did poorly on a test and think the reason for your poor performance is because the teacher asked tricky, unfair questions, you may become angry at your teacher. But, you obviously can't yell at your teacher (really, you can't), hit your teacher, or express your angry in any other hostile way toward the teacher, so you go home and "displace" your anger by punching your little brother instead.
( psych.) - Defense mechanism. Redirection of emotion. A person may become angry with their boss, and take their anger out on a co-worker. Assaulting innanimate objects is displacing frustration and anger in a “safe” fashion. ( see also “sublimation”) N O U V W X menu
In psychoanalytic theory, a redirection of an impulse from a channel that is blocked into another, more available outlet (e.g., displaced aggression, as in a child who hits a sibling when punished by her parents).
In psychology, displacement is a subconscious defense mechanism whereby the mind redirects affect from an object felt to be dangerous or unacceptable to an object felt to be safe or acceptable. For instance, some people punch cushions when angry at friends; a college student may snap at their roommate when upset about an exam grade.
Displacement and substitution are two closely related terms which are used to describe situations where the effects of an intervention on a particular individual, group or area are only realised at the extent of other individuals, groups or areas. Consider, for example, the case of a programme to provide employment subsidies. In a firm which benefits from this programme, subsidised workers may take the place of unsubsidised workers who would otherwise have been employed by that firm. This is known as substitution. Alternatively, a firm benefiting from the employment subsidies may win business from other firms which do not participate in the scheme. Thus, the jobs created in the participating firm may be partly or wholly offset by job losses in other firms. This is known as displacement.
Displacement transactions permit the lateral movement of gas through a transportation network. The configuration of many pipelines is such that it may not be apparent whether a given movement of gas is forward or backward from the point of receipt. It can be argued that all transportation service is performed by displacement as the physical delivery of the same molecules of gas is impossible. See BACKHAUL.
The project should not cause significant displacement of jobs or market share in any other UK business. At the risk of over-simplification, the host market should be sufficiently dynamic and capable of supporting the forecast increase in output without excessively compromising the performance of existing competitors. If the alternative is to locate the project outside the UK, displacement is less of an issue (if at all). With this argument, it is normally accepted that additional capacity is to be created regardless of project location. The competitive outcome will not change as a direct result of public subsidy and the alternative is less attractive to the UK economy. Similarly, increased exports and import substitution reduce the effect of any displacement issues on the application.
The substitution of less expensive energy generation for more expensive generation. Usually this means reducing or shutting down production at a high cost thermal plant and using cheaper thermal generation and/or hydroelectric power when it is available.
In pipeline transportation, the substitution of a source of natural gas at one point for another source of natural gas at another point. Through displacement, natural gas can be transported by backhaul or exchange. In natural gas marketing, the substitution of natural gas from one supplier of a customer with natural gas from another competing supplier.
Substitution of more expensive energy generation by less expensive generation, typically by reducing or stopping production at a high cost thermal plant in favour of cheaper available thermal and/or hydroelectric generation.
The apparent change in position of objects in an aerial photograph which project above (or below) scale datum. This is a geometric feature of photography that is normal and in many cases useful to the interpretation process.
(1) The distance between the logging tool measure points for various parameters measured by a combination logging tool. Also, the correction necessary to record all parameters at the same depth reference.(2) Pertaining to the dipmeter, it is the vertical distance in the hole between equivalent responses measured at different quadrants in the hole.(3) Also refers to the replacement of a portion of the interstitial fluids by borehole fluids, near the borehole, during the invasion process.
Any shift in the position of an image on a photograph which does not alter the perspective characteristics of the photograph (i.e., shift due to tilt of the photograph, scale change in the photograph and relief of the objects photographed).
A process by which the atmosphere originally present in a confined space is shifted or replaced by another. A typical example is the accidental introduction of a heavier than air "displacing" gas such as argon into a confined space. The argon tends to form a density dependent layer near the bottom of the confined space which displaces the atmosphere previously present, frequently resulting in a hazardous oxygen deficiency.
The measured distance traveled by a point from its position at rest. Peak to peak displacement is the total measured movement of a vibrating point between its positive and negative extremes. Measurement units expressed as inches or millinches.
For purposes of this demonstration project, displacement means the movement via RIF procedures of a fully qualified employee into a position held by an employee of lower retention standing in the same or lower broadband level. The undue interruption standard of 5 CFR 351.403(a)(1) serves as the criterion to determine if an employee is fully qualified. In addition, to be fully qualified, the employee must meet DAWIA statutory requirements for the position, if applicable. (However, statutory waivers shall continue to apply.)
A vector quantity, commonly denoted by the vector , which reflects an objectâ€(tm)s change in spatial position. The displacement vector points from the objectâ€(tm)s starting position to the objectâ€(tm)s current position in space. If an object is moved from point to point in space along path AB, the magnitude of the objectâ€(tm)s displacement is the separation of points and . Note that the path an object takes to get from point to point does not figure when deining displacement.
In Newtonian mechanics, displacement is the vector that specifies the position of a point or a particle in reference to an origin or to a previous position. The vector directs from the reference point to the current position.
Displacement is a characteristic quality of otherwise anomalous cognition. It defines a statistical or qualitative correspondence between a stimulus and a set of responses that occurs independently of their normally perceptible spatial and temporal relationships. Since its identification as a parapsychological effect, it has informed a number of research approaches into psi, particularly for its psychological meaningfulness.
Camera displacements are a feature of Large Format studio cameras that allow the relationship between the film plane and the lens plane to be altered in order to alter and control the perspective of the image. By using displacements it is possible for example to look up at a building and keep the vertical sides of the building parallel without having the keystone effect normally experienced with a camera.Digital cameras do not work well with significant displacements. The control of perspective is often best left to be accomplished in Photoshop
The process, either official or unofficial, of people being involuntarily moved from their homes because of war, government policies, or other societal actions, requiring groups of people to find new places to live. Displacement is a recurring theme in the history of the Jewish people.
displacement reaction; replacement reaction; replacement. A reaction in which a fragment of one reactant is replaced by another reactant (or by a fragent of another reactant). Displacement reactions have the same number of products as reactants, and are described by equations of the form A + BC AB + C (single displacement) or AB + CD AC + BD (double displacement).
di-'splâ-sment/ An economic result of a wage mandate increase whereby workers the least skilled workers are replaced with higher skill workers attracted to the labor market by artificially high wages. While the government has the ability to mandate wages, it cannot mandate the skill level of the employees that firms choose.
A defence mechanism where an idea's emphasis, interest or intensity is liable to be detached from it and placed on to other ideas which were originally of little intensity but which are related to the first idea by a chain of association.
