Calculate the amount of liquid inside a partial filled round hopper tank. The upper part of this tank consist out of a cylinder with a truncated funnel attached to the bottom. 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
cV = 𝝅(D/2)*H fV = 1/3𝝅H((T/2)²(B/2)²) where cV is the volume of the cylinder fV the volume of the truncated funnel fV the volume of the funnel D the diameter H is the height T and B the upper and lower diameters of the funnel
