The **Mass of a Spherical Tank Contents** calculator computes the mass or weight of substance (liquid or loose granular) contained in a spherical container based on the depth (d) of the substance, the radius of the spherical container (r) and the mean density (mD) of the substance.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**d**) Depth of liquid in the spherical tank. - (
**r**) Radius of the interior of the spherical tank. - (
**mD**) Mean density of the substance in the tank (default for water)

**Mass or Weight of Spherical Tank (M):** The mass of the sphere is returned in kilograms. However this can be automatically converted to other mass and weight units via the pull-down menu.

Mean Density of Common Substances

- 1,000 kg/m
^{3}- Pure Water - 1,022 kg/m
^{3}- Sea water - 1,037 kg/m
^{3}- Milk - 860 kg/m
^{3}- Olive Oil - 885 kg/m
^{3}- Diesel Fuel - 870 - 920 kg/m
^{3}- Crude Oil - 890 kg/m
^{3}- Fuel Oil - 789 kg/m
^{3}- Ethanol - 737 kg/m
^{3}- Gasoline (petrol) - 1,442 kg/m
^{3}- Cement Slurry

The spherical tank mass formula:

- uses the size of the tank, defined by its inner radius (
**r**), and the depth of the contained material (**d**), to calculate the volume of the contained substance in the spherical tank. - It then computes the mass by multiplying the volume by the mean density (
**mD**) to provide an estimate of the mass or weight of the contents of the container.

- Total or Partial Volume of a Box (Rectangular). For the partial volume, simply use the depth of substance in the container instead of the total depth of the container.
- Total or Partial Load Weight of a Box (Rectangular). For the weight of a partial load, simply use the depth of substance in the container instead of the total depth of the container.
- Volume of a Spherical Container
- Total or Partial Load Weight of a Spherical Container. For the total load weight, simply indicated the same value for the measure depth (D) of the substance to equal twice the radius (R) of the container. (See diagram)
