How to Calculate Horizontal Hemispheric Tank Volume in Imperial Units
Determine volume of a horizontal tank with hemispherical end caps in gallons and cubic feet. Enter diameter, barrel length, and fill height in inches or feet.
Example: a 4-foot diameter tank with 8-foot barrel and hemisphere ends holds about 1,045 gallons total. At 1.5 feet fill, it contains about 310 gallons.
Standard design for propane tanks, compressed gas vessels, and industrial pressure tanks.
