# Partial Volume in a Vertical Semi-Cylinder - Feet

Calculate the amount of liquid in a partially filled vertical semi-cylinder tank or container. The shape of this tank is a cylinder cut in half along its length, standing up straight.
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

### Vertical Semi - Cylinder Tank

#### Calculator

- enter the diameter of the vertical semi-cylinder tank in feet and or inches
- the height 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

It is the same formula for a full cylinder with the maximum height set as the radius.

V=0.5r²(Y-sin(Y))L+d(W-H)
where V is the volume
r the tank's height
Y=2cos^{-}¹(r-d)/d
d the depth of the liquid inside the tank
W the width of the tank
H the tanks height
