      Designation:

      ΔPp - pressure loss at various vane positions [Pa];
      ΔP - pressure loss [Pa];
      Кp – correction factor for pressure loss calculation depending on louvre deflection angle;
      LWA - sound power level [dB(A)];
      LWAO - sound power level for air pass 0,1 m2 [dB(A)];
      K - correction factor for sound power level calculation depending on air pass [dB(A)];
      Sap - air pass [m2];
      V - rated speed [m/s].
