Annular velocity is the speed of the drilling fluid's movement in a column called an annulus in oil wells. It is commonly measured in feet per minute (ft/min)...

variability The method measures annular velocities to and from the probe during the heart cycle. Annular velocities summarize the longitudinal contraction...

hole cleaning. Higher annular velocity improves cutting transport. Transport ratio (transport velocity / lowest annular velocity) should be at least 50%...

eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured. Unlike a lunar eclipse, which...

two devices Analog video AV Linux, a Linux-based operating system Annular velocity, speed of the drilling fluid's movement in a column called an annulus...

Today three main configurations exist: can, annular, and cannular (also referred to as can-annular tubo-annular). Afterburners are often considered another...

part of an annular fluidized bed, particular sized particles are separated by varying the velocity of feed gas. Consequently, at high velocity gas provides...

ratio, which is the ratio of mitral peak velocity of early filling (E) to early diastolic mitral annular velocity (E'). Diastolic dysfunction is assumed...

longitudinal displacements of the mitral annulus. The shapes of mitral annular velocity contours used to be approximated to be triangles, whose peak height...

effect is created by the introduction of a stream of high-velocity fluid into a low-velocity fluid, such as the hot gases emitted from a flame in air....

A continuous-rod warhead is a specialized munition exhibiting an annular blast fragmentation pattern, thus when exploding it spreads into a large circle...

through a common (mixed flow) propelling nozzle. The mixer reduces the velocity of the core exiting air, and consequently, reducing the amount of noise...

gradient between the two ends G = −⁠dp/dx⁠, the velocity distribution and the volume flux through the annular pipe are u ( r ) = G 4 μ ( R 1 2 − r 2 ) + G...

heterogeneous flow regime, and (4) annular flow regime. The homogeneous flow regime takes place at very low superficial gas velocity and can be divided into mono-dispersed...

velocity will be zero; this must be true if we are to use the annular ring approach; to assume otherwise would suggest interference between annular rings...

star's radial velocity or its profile of spectral lines. velocity dispersion The statistical dispersion of velocities about the mean velocity for a group...

observed that the velocity of the gas and liquid phases can be significantly different, depending on the flow pattern (e.g. plug flow, annular flow, bubble...
