An SPT test was conducted in a dry sand (no ground water table) with a unit weight of 18kN/m3. The drill rig used had an energy efficiency rating of 60%. The recorded blow counts were 6, 7 and 8. The depth of testing was 6 m. Use the Liao and Whitman (1986) correction for overburden stress to determine the corrected SPT value at this depth. N60=? CN=? (use 3 decimals) N1(60)=? (truncated to an integer value)
