FORMULAS

Key:
M = Mesh count
D = Wire Diameter
O = Opening Size
POA = Percent of Open Area

To Calculate Opening:
O =	1 - DM ------- M

To Calculate Mesh Count:
M =	1 ------- O + D

To Calculate Wire Diameter:
D =	1 - MO ------- M

To Calculate Percent of Open Area: POA = (OM)2 * 100

To Calculate Percent of Open Area: POA = (O/O+D)2 * 100

To Calculate Percent of Open Area: POA = (1-MD)2 * 100
