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
Area rule — The Whitcomb area rule, also called the transonic area rule, is a design technique used to reduce an aircraft s drag at transonic and supersonic speeds, particularly between Mach 0.75 and 1.2. This is one of the most important operating speed… … Wikipedia
flow rate — velocity of flow multiplied by cross sectional area of the river … Dictionary of ichthyology
Dimensionless momentum-depth relationship in open-channel flow — Contents 1 Momentum in Open Channel Flow 1.1 What is Momentum? 1.2 Momentum in a Rectangular Channel 1.3 Why is Momentum Important? … 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
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
Compressible flow — is the area of fluid mechanics that deals with fluids in which the fluid density varies significantly in response to a change in pressure. Compressibility effects are typically considered significant if the Mach number (the ratio of the flow… … Wikipedia
Collapsible flow — is a phenomenon that occurs in steady flow in tubes with significant distensibility, or the capability of swelling or stretching, under conditions of lower internal pressure relative to pressure outside the tube.[1] Such conditions occur rarely… … Wikipedia
Aortic valve area calculation — is an indirect method of determining the area of the aortic valve. The calculated aortic valve orifice area is currently one of the measures for evaluating the severity of aortic stenosis. A valve area of less than 0.8 cm² is considered to be… … 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
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
