Q = 4000 m³/h We select size 2000; H = 1250 Aef = 2 x 1.25 x 0.6944 = 1.74 (m²) vef = Q / (Aef x 3600) = 4000 / (1.74 x 3600) = 0.64 m/s LWA = 48 dB(A)
Q = 4000 m³/h Izberemo dimenzijo 2000; H = 1250 Aef = 2 x 1,25 x 0,6944 = 1,74 (m²) vef = Q / (Aef x 3600) = 4000 / (1,74 x 3600) = 0,64 m/s LWA = 48 dB(A)
