SCREEN CAPACITY CALCULATION - VIBFEM

By using Figure 13, the efficiency factor for any other screening efficiency can be obtained. For example, for a screen with 90% efficiency the factor is 1.0, and for a screen with 70% efficiency the factor is 1.2. The efficiency factor can also be used as a fudge factor for making calculated results agree with measured results.
