The following table shows the variation of the field standard penetration number (N60) in a sand deposit. The ground water table is located at a depth of 6m. The dry unit weight of sand from 0 to a depth of 6m is 20.6 kN/m3, use the suitable relationship to calculate the corrected standard penetration number. Also, use the suitable formula to calculate the soil friction angle.
