Hi all, this may have been covered all ready, but does anyone know how to calculate air pressure through perforated sheet, 27.5% and 50% free area? I have looked online but haven't been able to come up with much?? If it has been covered on the site already please could you point me in the right direction?

Any help welcome lol:001_tt2:

Thanks in advance Bradley
