Spike's Calculators

Calculate the amount of liquid in a partially filled round hopper tank. This tank has the shape of a cylinder with a truncated cone (funnel) bottom.

This calculator uses inches 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

- enter the top diameter (A) of the hopper tank in inches
- the cylinder height (A) in inches
- the cone (funnel) height (B) in inches
- the bottom diameter (B) in inches
- the depth of the liquid inside the tank in inches
- the weight of the liquid in pounds per US gallon

- the volume of the hopper tank in cubic inches
- the volume of the tank in cubic feet
- the volume of the tank in cubic metres
- 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

V = 0.5r²(Y-sin(Y))L+d(W-H) where V is the volume of the cylinder r half the tanks 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 V = d*𝝅/3*p²+pa+a² where V is the volume of the funnel d the fill height of the liquid 𝝅 = 3.14159265 p diameter @ fill height a half the tanks' bottom diameter

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)
