Average Flow Rate Garden Hose

Garden Hose Flow Rate and Time

The corporeality of h2o flow from a garden hose. This assumes a costless-flowing hose end (not connected to a sprinkler or something). The minutes to supply a given book is besides adamant beneath. Learn more than nigh the units used on this page.

Water Period Fourth dimension

The Equations

This period calculator uses the Hazen Williams equation to solve for flow bold that the pressure at the outlet is zero (open to atmosphere) and thus the entire pressure at the hose bib is dissipated by friction losses in the hose. The pressure level at the hose bib is causeless to exist the dynamic pressure (while water is flowing) not the static pressure (no water flowing). Annotation that at loftier flow rates the dynamic force per unit area at the hose bib often drops because of internal pressure losses in the h2o delivery organisation. The assumed C cistron (internal to the equation constant) is 135 for flexible garden hoses.

Water Flow Rate

Where:

= Water menstruum rate from the stop of the hose (gpm)

= Pressure at the hose bib while hose end is gratuitous flowing (dynamic pressure, not static pressure) (psi)

= Hose internal diameter (in)

= The hose length (ft)

Water Flow Time

Where:

= Time information technology will take to fill up the specified book (min)

= Book needed (gal)

= Flow charge per unit from the garden hose (gpm)
