Calculate pressure drop in compressed air pipe lines with a nomograph diagram.
The nomograph diagram below can be used to estimate pressure drop in compressed air pipe lines:
Example - Pressure Drop in Compressed Air Pipeline
The pressure drop in a compressed air pipe line
- length 100 m
- air flow 500 l/s
- inside diameter 100 mm
- working pressure 9 bar gauge
can be estimated in the diagram by drawing a line from the length line through the air flow volume line to the reference line. From the point on the reference line draw a line through the pipe diameter line to the reference line. From the working pressure line draw a line through the point on the reference line to the pressure drop line.
As indicated below the pressure drop can be estimated to 0.07 bar.
