# Partial Volume in a Horizontal Capsule Tank - Feet

Calculate the amount of liquid in a partially filled horizontal capsule tank or container.
The horizontal capsule tank is a cylinder with hemispherical heads on the ends. This calculator uses feet 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

##### Note:

The length measurement of the tank is the end to end length!

### Horizontal Capsule Tank - Feet

#### Calculator

- enter the diameter of the horizontal capsule tank in feet and or inches
- the length 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

Ve = 1/3πd²(3r-d)
Vc = Lr²Y-(r-d)√Dd-d²
where Ve is the volume of the two caps
Vc the volume of the cylinder part
L the length of the cylinder part
r half the Diameter
Y=2cos^{-}¹(r-d)/d
d the depth of the liquid inside the tank
D the diameter
