# Partial Volume in a Round Hopper Tank/Container - Metres

Calculate the amount of liquid inside a partial filled cylinder with funnel bottom tank. The upper part of this tank consist out of a cylinder with a truncated funnel attached to the bottom.

This calculator uses metres for measurements.

##### Approximate weight of Fuel or Water

one litre of water = 1 kilogram
one litre of diesel fuel = 0.832 kilogram
one litre of gas = 0.75 kilogram

#### Calculator

- enter the top diameter (A) in metres
- the cylinder part height (A) in metres
- the truncated funnel height (B) in metres
- the bottom diameter (B) in metres
- the depth of the liquid inside the tank in metres
- the weight of the liquid in kilograms per litre

#### Results

- the volume of the tank in cubic metres
- the volume in cubic inches
- the volume in cubic feet
- the total amount of liquid the tank can hold in litres
- the tank's capacity in hectolitres
- the tank's capacity in US gallons
- the amount of liquid inside the tank in cubic metres
- the amount of liquid inside the tank in cubic feet
- the amount of liquid inside the tank in litres
- the amount of liquid inside the tank in hectolitres
- the amount of liquid inside the tank in US gallons
- the amount of liquid inside the tank in Imperial Gallons
- the weight of the liquid inside the tank based on kilograms per litre
- the amount of liquid it will take to top up this tank in litres

##### Formula

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

##### Conversions

one cubic metre (m³) = 10 hectolitres (hl)
one cubic metre (m³) = 1000 litres (L)
one cubic metre (m³) = 61023.7440947323 cubic inches (in³)
one cubic metre (m³) = 35.3146667214886 cubic feet (ft³)
one cubic metre (m³) = 264.172052358148 gallons (gal) US
one cubic metre (m³) = 219.969248299088 gallons (gal) Imperial
