Designation:

ΔP_p - pressure loss at various vane positions [Pa];
ΔP - pressure loss [Pa];
К_p – correction factor for pressure loss calculation depending on louvre deflection angle;
L_WA - sound power level [dB(A)];
L_WAO - 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)];
S_ap - air pass [m²];
V - rated speed [m/s].
