Partial Volume in a Horizontal Cylindrical Tank with Hemispherical Heads
Calculate the amount of liquid in a partially filled horizontal cylindrical tank with hemispherical heads. This type of tank has the shape of a capsule.
This calculator uses inches for measurements.
Approximate weight of Fuel or Water
one US gallon of water = 8.34 pounds. one US gallon of diesel fuel = 7.1 pounds one US gallon of gas = 6 pounds
Note: The length measurement of the tank is the end to end length!

Formula
Ve = 1/3𝝅d²(3r-d)
Vc = Lr²Y-(r-d)√Dd-d²
where Ve is the volume of the two caps
Vc the volume of the cylinder part
L the length of the cylinder part
r half the Diameter
Y=2cos-¹(r-d)/d
d the depth of the liquid inside the tank
D the diameter
