Mass averaged velocity — is widely used concept in chemical kinetics. When more than one species in gaseous or liquid state flow together, they not only flow as a bulk, rather they have their own flow velocity too. The mass averaged velocity of any mixture is the… … Wikipedia
Mass flow rate — is the mass of substance which passes through a given surface per unit time. Its unit is mass divided by time, so kilogram per second in SI units, and slug per second or pound per second in US customary units. It is usually represented by the… … Wikipedia
Mass flow sensor — A mass airflow sensor. A mass air flow sensor is used to find out the mass flowrate of air entering a fuel injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the… … 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
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 sensor — A flow sensor is a device for sensing the rate of fluid flow. Typically a flow sensor is the sensing element used in a flow meter, or flow logger, to record the flow of fluids.As is true for all sensors, absolute accuracy of a measurement… … Wikipedia
Mass spectrometry — (MS) is an analytical technique that measures the mass to charge ratio of charged particles.[1] It is used for determining masses of particles, for determining the elemental composition of a sample or molecule, and for elucidating the chemical… … Wikipedia
flow — vb issue, emanate, proceed, stem, derive, *spring, arise, rise, originate Analogous words: emerge, *appear, loom: start, *begin, commence flow n Flow, stream, current, flood, tide, flux are comparable when meaning something issuing or moving in a … New Dictionary of Synonyms
Blood flow — is the continuous running of blood in the cardiovascular system. The human body is made up of several processes all carrying out various functions. We have the gastrointestinal system which aids the digestion and the absorption of food. We also… … Wikipedia
Choked flow — is a compressible flow effect. The parameter that becomes choked or limited is the velocity or the mass flow rate. Choked flow is a fluid dynamic condition associated with the Venturi effect. When a flowing fluid at a given pressure and… … Wikipedia
Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… … Wikipedia
