Redo Problem 3.5 using Eq. (3.14).

Problem 3.5

Following is the variation of the field standard penetration number (N₆₀) in a sand deposit:

Depth (m) .............. N₆₀
1.5 ............................. 6
3 ................................ 8
4.5 ............................. 9
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/m³, and the saturated unit weight of sand for depth 6 to 12 m is 20.2 kN/m³. Use the relationship given in Eq. (3.13) to calculate the corrected penetration numbers.
