A foundation pit is filled by silty clay, the control ${}_{c0}$ is $0\mathrm{.}92$

according to the requirement of relevant code. The maximum dry

density of the silty clay ${}_{\text{d}\text{m}\text{a}\text{x}}=2300k\frac{g}{m^3}$ in lab standard compaction test. On

the construction site, after compaction by flat roller, the density of compacted

soil $=2500k\frac{g}{m^3},$ and the water content $=17\%.(10$ points, results keep

two decimal$)$

Questions:

$(1)$ Calculate the dry density of compacted soil.

$(2)$ Calculate the compaction coefficient of compacted soil.

$(3)$ Judge if the density satisfies the requirement or not?
