Know gallons contained in a pipe run or tank cylinder before draining, filling, or chemical dosing
TECHNICAL UTILITY · PIPE_CYLINDER_VOLUME_GAL
Result
V_in3=π(id/2)²·L; gallons=V_in3/231
How to use this estimate
Circular cylinder internal volume V=π(r)²L with r=ID/2; US liquid gallon = 231 in³. Units: in³ / 231 → US gal. Out of scope as listed on this page. Screening / idealized model only — not a stamped design.
