Relational Table of Flow Rate / Velocity / Hose Size

Example :
  • The flow rate of your system requirement is 150cm3 per second. Connect your straight edge from the 150cm3 per second flow rate column to the recommended velocity range for pressure lines of 4 meters per second. The straight edge intersects at 04, so the recommended hose size is 04.

Conditions

Hose Length : 10m(Excluding Coupling Lengths)
Fluid : Hydraulic Oil
Kinetic Viscosity : 32.0mm2 /S

Pressure Drop Data

Example

Hose I.D.-12(19mm), Length 5m (with couplings at both ends) ,Kinetic viscosity 32mm2 /s , Flow rate 80ℓ/min

  1. By the flow rate 80ℓ/min and hose I.D-12,find the hose pressure loss as 0.2MPa from the graph above.
  2. Pressure loss of a coupling is about the same as 1/10 of that of the hose.
    Example
  3. 0.14MPa is estimated pressure loss of this hose assembly.
