Pressure drop in kg/m2 per 100 m compressed air pipelines can be estimated for some typical entering pressures in the diagrams below. The diagrams are calculated for schedule 40 pipes.
Other dimensions or pressures can be calculated with the
Compressed Air Entering Pressure 5 kg/cm2
- 1 kg/cm2 = 0.98 bar = 735 mmHg = 10000 mmH2O = 14.2 psi
- 1 m3/min = 0.017 m3/s = 60 m3/h = 1000 liter/min = 35.3 cfm
- 1 m (meter) = 3.2808 ft = 39.37 in
Compressed Air Entering Pressure 7.5 kg/cm2
Compressed Air Entering Pressure 10 kg/cm2
Compressed Air Entering Pressure 13 kg/cm2
Compressed Air Pressure Drop for Pipe Other than Schedule 40
Compressed air pressure drop in pipes other than schedule 40 can be calculated as
dp = dp40 (d40 / d)5 (1)
where
dp = actual pressure drop (bar per 100 m pipe)
dp40 = pressure drop in schedule 40 pipe from the table or diagram above (bar per 100 m pipe)
d40 = inside diameter schedule 40 pipe (inches)
d = actual inside diameter (inches)
