What sieve size is used to differentiate between coarse aggregate and fine aggregate for concrete $($choose one$)?$

A$.1$ inch

B$.$ #$200$

C$.$ #$8$

D$.$ #$4$

The following preliminary concrete mix has been designed assuming that the aggregates are in oven$-$dry condition:

Water $,305l\frac{b}{y}d3$

Cement $,693l\frac{b}{y}d3$

Coarse Agg. $,1,674l\frac{b}{y}d3$

Fine Agg. $,1,100l\frac{b}{y}d3$

The aggregates at the plant have the following properties:

Coarse Agg. $0\mathrm{.}5\%$ absorption$,2\%$ moisture content

Fine Agg. $,0\mathrm{.}7\%$ absorption$,6\%$ moisture content

The amount of water $(l\frac{b}{y}d3)$ that would be used in the final mix is most nearly $($show work, use additional paper if necessary$)$:

A$.206$

B$.222$

C$.305$

D$.388$

$14.$ A wood test specimen is $10$ inches wide. The width of the specimen is in the tangential direction of annual growth rings, and the length is in the longitudinal direction. Assuming a fiber saturation point of $30\%$ and an increase in moisture content from $15\%$ to $35\%,$ the new width of the specimen will be most nearly $($show work, use additional paper if necessary$)$:

A$.10\mathrm{.}5$ inch

B$.9\mathrm{.}6$ inch

C$.9\mathrm{.}5$ inch

D$.10\mathrm{.}4$ inch
