Barrel volume calculator is an online tool that calculates the volume of barrel by using radius and height of a barrel. It determines the barrel capacity at one click.
Barrel volume formula
The volume of a barrel can be found using the below equation.
Volume of barrel = πh(2R2 + r2)/3
Where,
h = height of barrel,
R = middle radius,
r = top and bottom radius.
How to calculate volume of a barrel?
To find barrel volume, follow the below example.
Example:
Find the volume of a barrel if its height is 2 ft, top and bottom radius is 0.4 ft, and middle radius is 0.8 ft.
Solution:
Step 1: Identify the values.
h = 2 ft, r = 0.4 ft, R = 0.8 ft
Step 2: Place the values in barrel volume formula.
V = πh (2R2 + r2)/3
V = 3.14159 × 2 (2 × 0.82 + 0.42)/3
Volume of barrel = 3.016 cubic feet
If you want to calculate how many gallons are in a barrel, multiply the volume in cubic feet with 7.480507.
