The amount of water displaced by a boat, i.e. the weight of the boat. Also, a type of hull that moves by displacing water rather than riding on top of it or planing.
The total cylindrical volume through which the pistons of an engine move during one stroke; often referred to as cubic inch displacement or CID.
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.
Volume obtained by multiplying area of cylinder bore by length of piston stroke.
1. The change in position of a body or point with respect to a reference point. 2. The volume swept out by a piston as it moves inside a cylinder from one extreme of its stroke to the other extreme.
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.
The weight of a ship, which is determined by the amount of water displaced by the ship.
The volume vacated by the piston of an engine as it moves downward in its cylinder.
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 volume swept out by the piston or rotor(s) per unit of time, normally expressed in cubic feet per minute.
The mass of a vessel and everything it contains. The vessel has different values of displacement drafts.
Displacement is the theory of how much the total volume of air-fuel mixture a car’s engine is capable of drawing on all cylinders during one operating cycle of the engine.
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.
The weight of the water displaced by a floating boat which is equal to the its weight
The total weight of the vessel, ie the amount of water the vessel will displace.
the weight of the ship in fully loaded condition.
The weight of the quantity of water displaced by the vessel. The displacement of the vessel on her light draft represents the weight of the vessel ready for use including stores etc.
the weight of the water displaced by the boat
The amount of liquid transferred from the inlet of the pump to the outlet in a single revolution. Displacement can be fixed or variable.
The amount of fluid that passes through a pump, motor or cylinder in a period of time or during a single actuation event, such as a revolution or stroke.
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.
The weight, in tons of 2,240 pounds, of the vessel and its contents. Calculated by dividing the volume of water displaced in cubic feet by 35, the average density of sea water.
The weight of water displaced by a floating vessel.
The weight of the water displaced by the vessel. Salt water equals 64 pounds per cubic foot.
the weight of water displaced by a ship floating in a given condition; a measure of ships size
Amount of air (in cfm) displaced by the compressor piston under no load, discharging directly to the atmosphere.
In an engine, displacement is the total volume of air-to-fuel mixture that an engine theoretically is capable of drawing into all cylinders during one operating cycle.
The volume displaced per unit of time, and in North America is usually expressed in cubic feet per minute.
The volume of fluid a pump moves in one cycle. The volume of fluid in a cylinder at full stroke.
The weight of water displaced by a hull. Also, a type of hull that smoothly displaces water as opposed to riding on top of it.
The volume of an engine’s cylinders, a general indicator of its size and power Read more
The total volume of air that is displaced by all pistons as the engine turns through one complete revolution.
Maximum engine cylinder piston sweep volume (bore & stroke) during a complete cycle, expressed in cubic inches, cubic centimeters or liters.
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!)
A term used to describe an engine's size. In general, the bigger an engine's displacement, the more powerful it is.
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.
Usually refers to the combined volume of the piston chambers - that is, the maxium volume of fuel and air that an engine can hold before compression takes place.
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 volume displaced by the compression element of the first stage per unit of time.
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.
The amount (weight) of water displaced by the boat or diver when floating.
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).
