Practice $2$

A sieve analysis was conducted on a $q,$ gram nample of a milk powder. The reaulis are provided in the table.

a$)$ Calculate the percentage passing for each sieve.

b$)$ Plot the cumulative smaller fraction versus particle size.

c$)$ Plot the percentage passing versus particle size.

d$)$ Calculate the span value of milk powder with equation "Span $=\frac{D_{\text{g}\text{o}\text{s}}-D_{104}}{D_{\text{s}\text{o}\text{m}}}"$ where Dyons. Dsos and $D_{10}$ are the particle diameters at $90,10,$ and $50\%$ cumulative volume.
