qV
  • 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
