The water is heated and then routed into a reduced-pressure flash evaporation "stage" where some of the water flashes into steam. This steam is subsequently condensed into salt-free water. The residual salty liquid from that first stage is introduced into a second flash evaporation stage at a pressure lower than the first stage pressure.
A flash flood in Canandaigua, New York in 2017, greatly inundates a small ditch, flooding barns and ripping out newly installed drain pipes. The United States National Weather Service gives the advice "Turn Around, Don't Drown" for flash floods; that is, it recommends that people get out of the area of a flash flood, rather than trying to cross ...
Flash is recorded as being a dialectal word from Cheshire describing the water-filled depressions caused by subsidence. Some have said that word was used as far back as the 17th century when describing small bodies of water across Cheshire, and was derived from a French word for puddle (today's flaque). [2]
A flash flood is a rapid and sudden flooding of low-lying areas. It typically occurs within a few hours, often even minutes, of heavy rainfall. This makes flash floods extremely dangerous as there ...
Multi-stage flash distillation (MSF) is a water desalination process that distills sea water by flashing a portion of the water into steam in multiple stages of what are essentially countercurrent heat exchangers. Current MSF facilities may have as many as 30 stages. [1]
Heavy rains Saturday brought flash flooding to Ravenna Township and other spots in Portage County after a National Weather Service issued a warning just before 1 p.m.
Historic rainfall triggered flash floods in northern Texas overnight, leaving vehicles partially submerged along a highway in Dallas early Monday.
When water freezes quickly, as in flash freezing, there are more nucleation sites, and more, smaller crystals. This results in much less damage to cell walls, proportional to the rate of freezing. This is why flash freezing is good for food and tissue preservation.
