The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...
Pipe is usually delivered to a customer or jobsite as either "sticks" or lengths of pipe (typically 20 feet (6.1 m), called single random length) or they are prefabricated with elbows, tees and valves into a prefabricated pipe spool [A pipe spool is a piece of pre-assembled pipe and fittings, usually prepared in a shop so that installation on ...
Within industry, piping is a system of pipes used to convey fluids ( liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid. [ 1][ 2] Industrial process piping (and accompanying in-line components) can be manufactured from wood, fiberglass, glass, steel, aluminum ...
Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...
Glassblowing. A glassworker blows air into the glass, creating a cavity inside. Glassblowing is a glassforming technique that involves inflating molten glass into a bubble (or parison) with the aid of a blowpipe (or blow tube). A person who blows glass is called a glassblower, glassmith, or gaffer. A lampworker (often also called a glassblower ...
glass bottle filled with carbon tetrachloride or similar fire extinguishing fluid; meant to be thrown and shatter at base of fire to mix with air to produce non-combustible mixture; Similar to extinguishers made of glass fixtures with spring-loaded clapper released by heat-fusible link. Limited effectiveness, and phased out in the 1950s when ...
In glassblowing, the term blowpipe refers to a pipe used to blow a bubble of air into a gather of molten glass, as the first step in the creation of hand-blown glass bottles and bowls. By the end of the first century, the two primary glassblowing tools were the iron blowpipe and pontil . [ 2 ]
Evidence of the use of the blown plate glass method dates back to 1620 in London and was used for mirrors and coach plates. Louis Lucas de Nehou and A. Thevart perfected the process of casting polished plate glass in 1688 in France. Prior to this invention, mirror plates, made from blown "sheet" glass, had been limited in size.
