Perforation Patterns
Below you will find some examples of typical perforation patterns:
|
circular perforation; triangular 60° |
square perforation; staggered 45° |
|
open area s = 0,906 (d/a)² |
open area s = 0,906 (d/a)² |
|
circular perforation; straight 90° |
rectangular perforation, straight |
|
open area s = 0,785 (d/a)² |
open area s = (c1*c2) / (a1*a2) |
|
circular perforation; staggered 45° |
rectangular perforation; staggered |
|
open area s = 0,785 (d/a)² |
open area s = 2 * (c1*c2) / (a1*a2) |
|
square perforation; straight 90° |
slotted perforation; straight |
|
open area s = (c/a)² |
open area s = ((c1*c2) - 0,215*c1²) / (a1*a2) |
|
square perforation; staggered |
slotted perforation; staggered |
|
open area s = (c/a)² |
open area s = 2 * ((c1*c2) - 0,215*c1²) / (a1*a2) |
