  3.15In a site consisting of normally consolidated clean sands,the water table is at 10 ft depth. The average unit weight ofthe sand above and below the water table is 111.5 lb/ft3 and125.0 lb/ft3, respectively. At a 25 ft depth, Nso was reportedas 26. Determine the following:a. (N160 using Liao and Whitman's (1986) equation for CN[Eq. (3.13)]b. D, using Skempton's (1986) correlation [Eq. (3.28)]c. Friction angle using Schmertmann's (1975) correlation[Eq. (3.30)]d.
