Engine displacement, or piston displacement, is the volume moved by an engine’s pistons in one revolution. It’s directly proportional to an engine’s power and is calculated based on the number of cylinders, bore, and stroke. The larger the bore and stroke, the greater the displacement and horsepower. However, variable displacement engines have become more prevalent, […]
A volumetric flowmeter measures fluid flow by placing an obstruction in the flow path that displaces a known amount of fluid. It can accurately measure a wide range of fluids, but is sensitive to dirty or corrosive fluids. It is widely used in commercial and domestic applications. A volumetric flowmeter is an instrument that measures […]
Displacement ventilation directs fresh air from floor to ceiling, providing energy savings, less noise, and fewer drafts. It requires a high ceiling and works best in temperate climates. Mixed-flow ventilation injects air high into the room, requiring cooler air temperatures and producing more noise. Displacement ventilation is a method of directing the flow of fresh […]
Displacement reactions involve the exchange of elements or groups in chemical compounds. Single shift reactions involve the replacement of a less reactive element with a more reactive one, while double shift reactions occur between ionic compounds. Acid-base reactions are a common form of double shift. Examples include metal plating, the production of hydrogen gas, and […]
