The US national average residential water use is about 80-100 gpd per person; a reverse-osmosis membrane module is rated in gpd (50-100 gpd for domestic units). 1 US gpd ≈ 4.381×10⁻⁸ m³/s.

About US fluid ounces per minute

The US fluid ounce per minute (fl oz/min) equals 3.785411784×10⁻³/128/60 ≈ 4.929×10⁻⁷ m³/s. It is found in US consumer-product flow specifications such as showerhead flow ratings, beverage dispenser settings, and fuel-injector bench tests in US automotive workshops. A showerhead rated at 48 fl oz/min delivers exactly 1.5 US gal/min. 1 fl oz/min ≈ 4.929×10⁻⁷ m³/s.
