WebBOLD MR (17% ± 14 [hypercapnia] vs 14% ± 24 [adenosine]; P = .80) and coronary blood flow velocity (21% ± 16 [hypercapnia] vs 26% ± 27 [adenosine]; P > .99) responses were similar to that of adenosine infusion. BOLD MR signal changes in canines with LAD stenosis during hypercapnia and adenosine infusion were not different (1% ± 4 ... In continuum mechanics the flow velocity in fluid dynamics, also macroscopic velocity in statistical mechanics, or drift velocity in electromagnetism, is a vector field used to mathematically describe the motion of a continuum. The length of the flow velocity vector is the flow speed and is a scalar. It is also called velocity field; when evaluated along a line, it is called a velocity profile (as in, e.g., law of the wall).

WebThis flow rate calculator uses flow velocity and cross-sectional flow area data to determine the volumetric flow rate of liquid. You can calculate the flow rate in five simple steps: Select the shape of the cross-section of the channel. Input all the measurements required to compute the cross-sectional area. Input the average velocity of the flow. WebThe speed of this flow has multiple meanings.
