The calculation of the void E% that remains after the perforation of the sheet metal (air) is derived from the following formulas:
Τhe open area Ε% is ascertained by means of the following formulars:
Where: Φ=hole diameter, T and T1=hole center distance, E%=opening percentage. Where: Φ=hοle diameter, Τ and Τ1=pitch, Ε%= open area.
