Hose Sizing

Hydraulic Hose Sizing

  • Flow speeds at the lower end of the ranges should be used when designing for a continuous duty system. The inside diameter of the hoses should be chosen such that the needed flow rates can be supplied at fluid speeds within the acceptable ranges listed above.

  • The following equation can be used to relate flow desired flow rate
    to hose diameter:

  • Where Q is fluid flow rate in gallons per minute, D is the inside diameter of the hose in inches and V is fluid speed in feet per second.
