  • mahuvoo kiiruse (kohaliku vedeliku kiiruse aksiaalsete komponentide integraal üle toruava ristlõike) ja mõõteristlõike pindala suhe
  • ratio of the volume flow-rate (the integral over a cross-section of the conduit of the axial components of the local fluid velocity) to the area of the measurement cross-section
vedeliku keskmine telgkiirus
Usage examples
  • Vedeliku keskmine telgkiirus on vedeliku keskmine kiirus torus, mis tavaliselt tähendab vookiirust jagatuna voo ristlõikepindalaga ja kui voog on ebastabiilne, nõuab keskmine telgkiirus tavaliselt ka keskmise aja kasutamist

mean axial fluid velocity
Usage examples
  • The mean axial fluid velocity is the mean velocity of a fluid in a pipe normally means the flow rate divided by the cross-sectional area of the flow. If the flow is unsteady, then mean velocity usually means time averaged as well.
