hello all.glad to be here!(adsbygoogle = window.adsbygoogle || []).push({});

please in the attached document, column 5 and 6 which represents the differential and cumulative frequency distributions were obtained using equations (5) and (6). I'll be mighty grateful if anyone can give me a step by step breakdown of how it was done?? Many thanks

pls note: x is the mass fraction of the Rejection g (column 2)

D is the arithmetic mean of the nominal size
