Q$1(30$P$)O{C}_1$ and $PC1,PC2.$

A $150mm$ diameter exploratory boring has been drilled through fine sand to a depth of $5\mathrm{.}7m.$ An SPT$-$N value of $24$ was obtained at this depth using a USA Donut hammer with a standard sampler. The groundwater table is at a depth of $3\mathrm{.}3m.$ The unit weight of sand is $18k\frac{N}{m^3}.$ Compute $N_{60},(N_1{)}_{60},$ and ${}^{\text{'}}$ at the test location.
