  • vookogus, Q = dV/dt, kus V on tegelik voomaht ja t on aeg, mis kulus selle voomahul arvesti läbimiseks
  • voomuunduri ristlõiget läbinud voolava keskkonna vookoguse suhe selle ristlõike läbimiseks kulunud ajaga
  • flow rate, Q = dV/dt, where V is actual volume of flow and t is time taken for this volume to pass through the meter
  • ratio of the quantity of fluid passing through the cross-section of the flow sensor and the time taken for this quantity to pass through this section
  • mass or volume of fluid passing through the primary device per unit time
  • quotient of the quantity of fluid passing trough the cross-section of a conduit and the time taken for this quantity to pass through this section
voog preferred
Usage examples
  • Voog on suurus, mis iseloomustab ajaühikus voolava keskkonna mahtu või massi, mis on oluline vedeliku dünaamika ja inseneriteaduse jaoks.
  • Püsivoo ja soojusarvesti voo alampiiri suhe on tavaliselt 5, 10, 25, 50, 100 või 250.

  • ruumiline maht mõõtetingimustel jagatud ajaga
  • voolava keskkonna vookogus, mis on väljendatud mahuna
  • quantity equal to the volume dV of substance crossing a given surface during a time interval with infinitesimal duration dt, divided by this duration, thus qV = dV / dt
  • flow rate in which the quantity of fluid is expressed as volume
  • volume at metering conditions divided by time
  • volume of fluid passing through the primary device per unit time
mahuvoog preferred
Usage examples
  • Mahuvoo mõõtmisel on vaja märkida rõhk ja temperatuur, mille juures ruumala/mahtu mõõdetakse.
Good to know
  • Madalate häirete katse viiakse läbi õhuga atmosfääritingimustes mahuvool 0,25 Qmax, 0,4 Qmax ja Qmax.
