# Partial Volume in a Hemisphere Dome Tank/Container

Calculate the amount of liquid inside a partial filled hemispherical dome tank.
The dome 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 US gallon of water = 8.34 pounds.
one US gallon of diesel fuel = 7.1 pounds
one US gallon of gas = 6 pounds
```

#### Calculator

1. enter the tank's base length
2. the depth of the liquid inside the tank in inches
3. the weight of the liquid in pounds per US gallon

#### Results

1. the volume of the dome tank in cubic inches
2. the volume of the tank in cubic feet
3. the volume of the tank in cubic metres
4. the total amount of liquid the tank can hold in US gallons
5. the amount of liquid inside the tank in US gallons
6. the amount of liquid inside the tank in Imperial gallons
7. the amount of liquid inside the tank in litres
8. the amount of liquid inside the tank in cubic feet
9. the weight of the liquid inside the tank based on lbs/gal US
10. 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
```
