The Volume of Capsule Tank calculator computes the volume of a capsule shaped container, 
Capsule Shaped Tank also known as a spherocylinder based on the dimensions of the tank. See diagram.
INSTRUCTIONS: Choose units and enter the following:
- (D) Diameter of the central cylinder.
- (L) Total Length of the capsule
Capsule Tank Volume (V): The calculator returns the volume in gallons. However this can be automatically converted to other volume unite (e.g. liters, cubic meters) via the pull-down menu.
The Math
CONTAINER SHAPES
Conic Cylinder Capsule Shaped
Box Container 
Spherical Tank
Geometrically, a capsule is a central cylinder with hemispheres (half spheres) on each end. The volume is simply the sum of the volume of the central cylinder and the complete sphere. Both ends added create a complete sphere.
