App description

Barrel area calculation:

For parabolic barrels

\(V= \frac {πl}{15} (2D^2+Dd+ \frac {3}{4} d^2\)

For round barrels

\(V= \frac {πl}{12} (2D^2+d^2)\)

In formula：

• D——Intermediate section diameter
• d——Bottom diameter
• l——Bucket height

Usage example

Input data:

D—intermediate section diameter: 15

D—bottom diameter: 10

l—Barrel height: 8

Parabolic barrel volume: 1130.97

Round barrel volume: 1151.91
