Flow-accelerated corrosion — (FAC), also known as flow assisted corrosion, is a corrosion mechanism in which a normally protective oxide layer on a metal surface dissolves in a fast flowing water. The underlying metal corrodes to re create the oxide, and thus the metal loss… … Wikipedia
Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… … Wikipedia
Normally closed — In electronics, a normally closed (abbreviated NC) switch is one that normally allows current to flow and which prevents current flow when it is perturbed. A switch that is closed conducts electricity. Normally closed switches are often spring… … Wikipedia
Flow control valve — Globe control valve with the pneumatic actuator and smart positioner A flow control valve regulates the flow or pressure of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature… … Wikipedia
Normally open — In electronics, a normally open switch is one that normally prevents current flow and which allows current to flow when it is perturbed. Such a switch requires a constant intervention in order to keep it closed.ee also*Normally closed *Relay … Wikipedia
Flow chemistry — In flow chemistry, a chemical reaction is run in a continuously flowing stream rather than in batch production. In other words, pumps move fluid into a tube, and where tubes join one another, the fluids contact one another. If these fluids are… … Wikipedia
Flow battery — A flow battery is a form of rechargeable battery in which electrolyte containing one or more dissolved electroactive species flows through a power cell / reactor that converts chemical energy to electricity. Additional electrolyte is stored… … Wikipedia
