Residence time — is a broadly useful concept that expresses how fast something moves through a system in equilibrium. It is the average time a substance spends within a specified region of space, such as a reservoir. For example, the residence time of water… … Wikipedia
Residence Time Distribution — The residence time distribution (RTD) of a chemical reactor is a probability distribution function that describes the amount of time a fluid elements could spend inside the reactor. Chemical engineers use the RTD to characterize the mixing and… … Wikipedia
Baseflow residence time — (often mean baseflow residence time) is a parameter useful in describing the mixing of waters from the infiltration of precipitation and pre event groundwater in a watershed. It describes the average amount of time that water within the transient … Wikipedia
Chemical reactor — In chemical engineering, chemical reactors are vessels designed to contain chemical reactions. The design of a chemical reactor deals with multiple aspects of chemical engineering. Chemical engineers design reactors to maximize net present value… … Wikipedia
chemical industry — Introduction complex of processes, operations, and organizations engaged in the manufacture of chemicals and their derivatives. Although the chemical industry may be described simply as the industry that uses chemistry and… … Universalium
Chemical kinetics — Reaction rate tends to increase with concentration a phenomenon explained by collision theory. Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how… … Wikipedia
Chemical Warfare Brigade — is a rock opera created by Marc Brownstein of the trance fusion band The Disco Biscuits. It was written during Marc Brownstein s dismissal from the band and was debuted by Electron. Since the Disco Biscuits rarely play a full Chemical Warfare… … Wikipedia

Lake retention time — (also called the residence time of lake water, or the water age or flushing time) is a calculated quantity expressing the mean time that water (or some dissolved substance) spends in a particular lake. At its simplest this figure is the result of … Wikipedia
hydrosphere — /huy dreuh sfear /, n. the water on or surrounding the surface of the globe, including the water of the oceans and the water in the atmosphere. [1885 90; HYDRO 1 + SPHERE] * * * Discontinuous layer of water at or near the Earth s surface. It… … Universalium
Plug flow reactor model — The plug flow reactor (PFR) model is used to describe chemical reactions in continuous, flowing systems. The PFR model is used to predict the behaviour of chemical reactors, so that key reactor variables, such as the dimensions of the reactor,… … Wikipedia
