| 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% |
