Diagram 2 displaying the overall length and cut length of a hose assembly
The arrow on drawing D2 denotes the 'R' measurement showing the 'Minimum Bore Through Fittings (mm)' which is reduced through the fitting tail, with a tolerance of +/- 0.2mm. The below measurements represent the minimum bore of each DN size; however, fittings will vary in bore size. For further information regarding this please contact out technical department.

Formula: Pc = (TxL) + R (in mbar)


Pc = Pressure Drop in mbar
T = Pressure drop in mbar for one meter of hoses according to its flow capacity in M3/h (Schedule 1)
L = Hose Length in meters
R = Pressure drop in mbar caused by two fittings (male x female), same condition than 'T' (Schedule 2)

Flexible hose with one straight and one elbow fittings= R x 1.5
Flexible hose with two elbow fittings = R x 3
Example:
Flexible hose DN13 length 500mm 1 FP - MC, flow capacity 1000 l/h
Pc = (26 mbar/m x 0.5m) + 23 mbar = 36 mbar
Flexible hose DN25 length 800 1 FP - FPN, flow capacity 1500 l/h
Pc = (3mbar/m x 0.8m) + (2.5 mbar x 1.5) = 9 mbar

Note: 'T' value only valid for hoses installed straight. Installation with bend can cause pressure drop relative to decrease in bend radius.
