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 feet for measurements.
one US gallon of water = 8.34 pounds. one US gallon of diesel fuel = 7.1 pounds one US gallon of gas = 6 pounds
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 centimetres, with a liquid depth of 11 centimetres, this tank is full.
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
