Laboratory Determination of Hydraulic Conductivity

Hydraulic conductivity is the measure of flowability of water inside the soil in the presence of a hydraulic gradient. The hydraulic gradient is defined as the difference in the water heads in the soil, which induces a water motion. In simple terms, a hydraulic gradient is the presence of a potential that induces a flow of water.

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)
