Applications
The circle packing calculator can be used for various engineering and industrial applications, including estimating:
- The number of small pipes that fit into a large pipe or tube.
- The number of wires possible in a conduit.
- The number of fibers that fit in a connector.
Iterative Method for Bundle Diameter
The outside diameter of a pipe bundle can be approximated by iteratively adjusting the large pipe diameter input until the calculated number of pipes matches the desired bundle count. The following table shows an example iteration for 30 pipes with a 1.5-inch diameter.
Iteration No. | Small Pipe Diameter(in) | Large Pipe Diameter(in) | No. of Pipes |
|---|---|---|---|
| 1 | 1.5 | 10 | 32 |
| 2 | 1.5 | 9 | 26 |
| 3 | 1.5 | 9.8 | 31 |
| 4 | 1.5 | 9.6 | 29 |
| 5 | 1.5 | 9.7 | 31 |
| 6 | 1.5 | 9.65 | 30 |
