Open area % from any two of mesh / opening / wire, plus total surface and open area for a circular or rectangular screen.
Enter any two of mesh, opening and wire diameter, or mesh alone for a standard-chart estimate.
Calculates percent open area from any two of mesh, opening and wire diameter, plus total and open area for round or rectangular decks, assuming a plain square weave. Open area is a geometric figure: effective throughput also depends on blinding, near-size particles, motion and material condition, so treat it as a comparison metric rather than a capacity prediction.
