Size distribution function relationships among

The characteristic separation curve can be deterrnined for any size separation device by sampling the feed, and coarse and fine streams during steady-state operation. A protocol for determining such selectivity functions has been pubHshed (4). This type of testing, when properly conducted, provides the relationships among d K, and a at operating conditions. These three parameters completely describe a size separation device and can be used to predict the size distribution of the fine and coarse streams. 

The fact that or 2 can be used as the independent variable for the log normal distribution creates confusion among students because the log normal density function can take on different forms depending on which variable is used. Thus, if we let jc be the actual particle size and z be the In transformation then we have the following relationships ...
