Standard penetration test was performed in a 6” diameter boring at a depth of 25ft below the ground surface. The driller used a US-style donut hammer and a standard SPT sampler. The actual blow count, N, was 17. The soil is a normally consolidated fine sand with a unit weight (y) of 115.0 lb/ft³ and D50 = 0.4 mm.The groundwater table is at a depth of 40 ft. Compute the following:
