Flow rate measurement qV (m³/h, m
3
/s)
The flow rate qV is calculated by multiplying the effective intake velocity Vk (m/s), measured using a hot-wire anemometer or a pitot tube, by the actual
section Ak (m²) shown in the table at the side.
Ak - values (m²)
Size Ak
AIRJET 50/I 0,0062
AIRJET 80/I 0,00098
qv (m³/s) = vk x Ak
qv (m³/h) = vk x Ak x 3600
Pressure drop
Dp = pressure drop
Q = Air flow
