A concrete wall whose total volume will be $735$ cy is to be constructed by using job$-$mixed concrete to the following specifications.

Maximum aggregate size $=1(1)/(2)$

Maximum w$/$c ratio $=0\mathrm{.}6$

Minimum cement content $=6$ sacks$/$cy

Assume the percent of fine aggregate to be $32\%$ and $4\mathrm{.}5\%$ air voids. Find the amount of cement, coarse and fine aggregate in tons needed to cast the wall. Find the gallons of water needed per hour, assuming a concrete placement operation of $7$ hours.
