Equation (3.30) Following is the variation of the field standard penetration number (N) in a sand deposit: 70.34 6' = tan Depth (m) 12.2 + 20.3 1.5 6. 8 4.5 6. 8. 7.9 13 9 14 The groundwater table is located at a depth of 6 m. Given: the dry unit weight of sand from 0 to a depth of 6 m is 18 kN/m, and the saturated unit weight of sand for depth 6 to 12 m is 20.2 kN/m³. Use the relationship given in Eq. (3.30) to calculate the corrected penetration numbers.
