PRESSURE LOSS DIAGRAM PER 1 M STRETCHED AIR DUCT |
CALCULATION EXAMPLE: |
|
|
|
- Select a curve that matches the air duct diameter [mm], 200 mm in this case.
- Find the intersection point of this line with the vertical line of the required air flow in m3/h, 500 m3/h in this case.
- The horizontal line that shows the pressure loss in Pa per 1 m straight air duct crosses this intersection point.
- Multiply pressure loss value (2.4 Pa/m at 20°С) by total air duct length to get the total pressure loss value. To calculate pressure loss in case of bends consider each bend as extra air duct meter.
