Series SCDC SCDC Smoke Evacuation Damper Selection Chart SCDC Vp-ΔPest 100 90 80 70 Key Vp= damper air velocity in m/s. ΔPest= static pressure loss across the damper in Pa. Selection example: To calculate the static pressure loss across a damper for a given flow rate Q(m3/h) the air velocity Vp(m/s) is calculated in relation to the free area Al (dm2) of the damper as set out in the above table “Free area table in dm2” using the formula Vp=(Q/Al)/36. By entering this velocity in the previous table, the static pressure loss is obtained ΔPest. Example: for a flow rate of 2500 m3/h in a 500x300 SCDC...
