Geotechnical Engineering (UPVOTE WILL BE GIVEN. PLEASE ANSWER THE QUESTION CORRECLTY. NO LONG EXPLANATION NEEDED. FOLLOW THE INSTRUCTIONS CAREFULLY.) A moist soil weighed 895 g with a volume of 425 cm3. After drying, the sample weighed 775 g. Of the dried soil, 400 g was poured into a vessel loose state. Its volume subsequently determined to be 275 cm3. That same 400 g was then vibrated and tamped to a volume of 212 cm3 with Gs = 2.71. Determine the designation of the granular soil based on its relative density. (3 decimal places - Do not round off unless it's the final answer)

A fall cone test was carried out on a soil to determine the liquid and plastic limit using cone of mass 80gm. At 52% moisture content, the penetration was obtained as 15 mm. Estimate the liquid limit of soilusing single point method.If the same soil was used for the construction of core of an embankment dam, what would be therecommended range of moisture content to ensure the plastic behavior of soil and ensure propercompaction during construction. Plastic limit is 1/3rd of the LL value
Prob. A falling head permeability test was performed on a sample of silty sand. The time required for the head to fall in the standpipe from the 60 cm to 30 cm mark was 70 minutes. The sectional area of the standpipe was 1.25 cm?. If the height and diameter of the sample were respectively 100 mm and 90 mm, determine the value of K.
