Calculate the volume of a partial filled vertical capsule tank or container.
The vertical capsule tank is a cylinder with hemispherical heads on top and bottom.

This calculator uses metres for measurements.

Approximate weight of Fuel or Water

one litre of water = 1 kilogram
one litre of diesel fuel = 0.832 kilogram
one litre of gas = 0.75 kilogram

Calculation

1. enter the diameter of the vertical capsule tank in metres
2. the height of the tank in metres
3. the depth of the liquid inside the tank in metres
4. the weight of the liquid in kilograms per litre

Results

1. the volume of the tank in cubic metres
2. the volume in cubic inches
3. the volume in cubic feet
4. the total amount of liquid the tank can hold in litres
5. the tank's capacity in hectolitres
6. the tank's capacity in US gallons
7. the amount of liquid inside the tank in cubic metres
8. the amount of liquid inside the tank in cubic feet
9. the amount of liquid inside the tank in litres
10. the amount of liquid inside the tank in hectolitres
11. the amount of liquid inside the tank in US gallons
12. the amount of liquid inside the tank in Imperial Gallons
13. the weight of the liquid inside the tank based on kilograms per litre
14. the amount of liquid it will take to top up this tank in litres

Formula

Vt = π/12(3D²d-4d³)
Vc = π(D/2)²d
Vb = π/6(3Dd²-2d³)
where Vt is the partial volume in the upper head
Vc partial volume of the cylinder
Vb the partial volume in the lower head
D tank diameter
d the fill height of the liquid
