口径 (kǒujìng, "opening diameter") combines 口 (kǒu, "mouth or opening") + 径 (jìng, "diameter"), so it names the width across an object's opening.

Usage tips

  • In technical product descriptions, this word names a size specification, not the amount of liquid already moving; actual flow also depends on pressure and pipe design.
