Pressure loss diagram

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 °C) 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.
