# Partial Volume Hemisphere Dome Calculator - Feet

Calculate the amount of liquid inside a partial filled hemispherical dome tank or container.
The 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 feet and 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

#### Calculator

- enter the diameter of the tank in feet and or inches
- the depth of the liquid inside the tank in feet and or inches
- the weight of the liquid in pounds per US gallons

#### Results

- the volume of the tank in cubic feet
- the volume of the tank in cubic inches
- the volume of the tank in cubic metres
- the total amount of liquid the tank can hold in US gallons
- amount of liquid the tank can hold in litres
- the amount of liquid inside the tank in cubic feet
- 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 hectolitres
- 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= π/12(3d²f-4f³)
where V is the volume of liquid inside the tank
Π = 3.14159265
d the base length
f the depth of the liquid inside the tank
