Horizontal Cylindrical Tank with Hemispherical Heads (Capsule Tank)
Calculate the volume, capacity, and surface area of a horizontal cylindrical tank with hemispherical heads. The shape of the tank looks like 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: measurement used in the calculation is the diameter, not the radius ! The length measurement is the overall tank length, cylinder plus the two caps.
