Correction pen. A correction fluid is an opaque, usually white fluid applied to paper to mask errors in text. Once dried, it can be handwritten or handdrawn upon. It is typically packaged in small bottles, with lids attached to brushes (or triangular pieces of foam) that dip into the fluid. The brush applies the fluid to the paper.
Tipp-Ex. Tipp-Ex is a brand of correction fluid and other related products that is popular throughout Europe. It was also the name of the German company ( Tipp-Ex GmbH & Co. KG) that produced the products in the Tipp-Ex line. While Tipp-Ex is a trademark name for correction products, in some countries it has become a genericised trademark: [ 1 ...
Warman centrifugal pump in a coal preparation plant application. A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
An appeals court on Friday overturned the conviction and life sentence of a man found guilty of killing a U.S. Border Patrol agent whose death exposed the botched federal gun operation known as ...
Doré and his team produce fresh baguettes — added in 2022 to the U.N.’s list of intangible cultural heritage — and a variety of other bread cooked every day on site.
Mr. Pommel Horse has had quite the week. Stephen Nedoroscik, dubbed "Pommel Horse Guy" by the internet, became an Olympic bronze medalist Monday, then a meme. Now, he has an individual Olympic ...
Euler's pump equation. Based on Eq. (1.13), Euler developed the equation for the pressure head created by an impeller: (1) (2) Y th : theoretical specific supply; H t : theoretical head pressure; g: gravitational acceleration. For the case of a Pelton turbine the static component of the head is zero, hence the equation reduces to:
