flow data
air flow pressure loss
GENERAL INFORMATION
This table may be used to determine the pressure loss in hose connected to rock drills and pneumatic tools. It is correct for hose
with smooth inside lining. Hose with rough inside lining may have a friction loss of as much as 50% greater than the figures given
in the table.
For longer or shorter lengths of hose, the friction loss is proportional to the length, e.g., for 25 feet, half of the above; for 150
feet, three times the above, etc.
PULSATING FLOW
