| Flow can be measured as either a volumetric quantity or an instantaneous velocity. |
| Availability of the instantaneous velocity of a legged robot is usually required for its efficient control. |
| Thus, the difference quotient can be interpreted as instantaneous velocity or as the slope of a tangent to a curve. |
| In heterodyne SLDV, a scanned laser beam incident on the vibrating test surface undergoes a Doppler radial frequency shift proportional to the instantaneous velocity. |
| One hundred instantaneous velocity flow fields were computed for each phase. |
| Hot-wire anemometry is an experimental technique to measure instantaneous velocity and temperature fluctuations in flows. |
