      Opening   2    
Percent Open Area   =  
    X 100
      Opening + Diameter        
 
EXAMPLE 1
Assume an opening of 1/2" and a wire diameter of 1/8"
The above formula requires that all fractions of one inch must first be converted into their decimal equivalents therefore:
The opening of 1/2" = 1 divided by 2 = 0.50"
The wire diameter of 1/8" = 1 divided by 8 = 0.125"
 
1   Add the opening and wire diameter together. 0.50 + 0.125 = 0.625
2   Divide the result above of into the opening. 0.50 divided by 0.625 = 0.80
3   Square the above result (multiply by itself). 0.80 x 0.80 = 0.64
4   Multiply the result by 100. 100 x 0.64
5   The solution should be expressed as as: 64%
 
EXAMPLE 2
Assume an opening of 1.625" and a wire diameter of 0.244"
 
1   Add the opening and wire diameter together. 1.625 + 0.244 = 1.869
2   Divide the result above of into the opening. 1.625 divided by 1.869 = 0.8694
3   Square the above result (multiply by itself). 0.8694 x 0.8694 = 0.7558
4   Multiply the result by 100. 100 x .7558 = 75.58
5   The solution should be expressed as as: 75.58%
