# Partial Volume in a Bowl Tank

Calculate the amount of liquid inside a partial filled bowl tank.

The bowl tank here is in the shape of a half sphere (hemisphere) and the tank's height is equal to half the diameter. This calculator uses inches 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

#### Calculator

- enter the diameter of the bowl tank in inches
- the depth of the liquid inside the tank in inches
- the weight of the liquid in pounds per US gallon

#### Results

- the volume of the bowl tank in cubic inches
- the volume of the tank in cubic feet
- the volume of the tank in cubic metres
- the total amount of liquid the tank can hold in US gallons
- the amount of liquid inside the tank in US gallons
- the amount of liquid inside the tank in Imperial gallons
- the amount of liquid inside the tank in litres
- the amount of liquid inside the tank in cubic feet
- the weight of the liquid inside the tank based on lbs/gal US
- the amount of liquid it will take to fill this tank in US gallons

##### Formula

V = 𝝅rd²-𝝅/3d³
where V is the volume of liquid inside the tank
𝝅 = 3.14159265
r half the diameter
d the depth of the liquid inside the tank
