If your air line is between 1 2 i d.
Air pressure line loss.
Example pressure loss in compressed air hose.
Don t forget your compressed air fittings.
From the second diagram above we can estimate the friction loss to be approximately 0 4 psi 50 ft.
Then assume 5 loss per 100 of air line.
L length of pipe m.
1 kg cm 2 98068 pa 0 98 bar 0 97 atmosphere 736 mm hg 10000 mm h.
The friction loss in a 10 ft hose can be calculated as 0 4 psi 50 ft 10 ft 50 ft 0 08 psi.
Includes 53 different calculations.
To illustrate the dramatic difference pipe hose diameter makes on pressure loss let s use this tool to compare 100ft long pipes with internal diameters of and 1 for 70cfm fad free air delivery of compressed air delivered at 100 psi gauge pressure equivalent to 114 7 psi absolute pressure at the upstream hose entrance.
