SUP-LUGB Vortex flowmeter wafer installation

• Kev ntsuas txoj cai

  Cov kua dej ntws nrog qee qhov nrawm thiab dhau qhov kev cuam tshuam ruaj khov tsim cov vortices.Lub cim ntawm vortices yog hu ua Karman's Vortices.Qhov zaus ntawm vortex shedding yog ib qho kev ua haujlwm ncaj qha ntawm cov kua dej tshaj tawm thiab zaus nyob ntawm cov duab thiab lub ntsej muag dav ntawm lub cev bluff.Txij li qhov dav ntawm qhov thaiv thiab sab hauv txoj kab uas hla ntawm cov yeeb nkab yuav ntau dua los yog tsawg, qhov zaus tau muab los ntawm kev qhia:
  f=(St*V)/c*D
