Partial Volume in a Horizontal Semi-Cylinder Tank
Calculate the amount of liquid in a partially filled horizontal semi-cylinder tank/container. The horizontal semi-cylinder tank represents the bottom part of a cylinder split in half along its 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
Note:
In this type of tank, the maximum depth of the liquid inside the tank is half the diameter measurement. For instance, if the diameter of the tank is 22 inches, with a liquid depth of 11 inches, this tank is full.

- 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
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
Conversions
one cubic inch (in³) = 0.000578703703703704 cubic feet (ft³) one cubic inch (in³) = 0.000016387064 cubic metres (m³) one cubic inch (in³) = 0.00432900432900432 gallons (gal) US one cubic inch (in³) = 0.00360465014990905 gallons (gal) Imperial one cubic inch (in³) = 0.016387064 litres (L)
