I need the answer soon as possible, please The following results were obtained from liquid limit and plastic limit tests conducted on the soil from Question 1. Please address the following points:a. **Draw the flow curve and determine the liquid limit.**b. **Calculate the plasticity index.**c. **Comment on the results obtained.**### Liquid Limit| Test No. | Number of Blows, N | Moisture Content (%) ||----------|--------------------|----------------------|| 1 | 34 | 186 || 2 | 26 | 143 || 3 | 22 | 109 || 4 | 14 | 80 || 5 | 9 | 67 |### Plastic Limit| Test No. | Moisture Content (%) ||----------|----------------------|| 1 | 34.5 || 2 | 37.6 || 3 | 35.3 || 4 | 36.8 |### Instructions for Analysis1. **Flow Curve and Liquid Limit:** - Plot the moisture content against the number of blows on a semi-logarithmic graph. - The liquid limit is the moisture content at which the soil changes from a plastic state to a liquid state, typically corresponding to 25 blows.2. **Plasticity Index:** - Calculate the plasticity index (PI) using the formula: PI = Liquid Limit - Plastic Limit.3. **Results Commentary:** - Analyze and interpret the results to understand the soil's behavior and properties.

Three groups of students from the Geotechnical Engineering class collected soil-aggregate samples for laboratory testing from a recycled aggregate processing plant in Palm Beach County, Florida. Three samples, denoted by Soil A, Soil B, and Soil C, were collected from three locations of the aggregate stockpile, and sieve analyses were conducted (see Figure 2.35). (a) (b) Figure 2.35 (a) Soil-aggregate stockpile; (b) sieve analysis (Courtesy of Khaled Sobhan, Florida Atlantic University, Boca Raton, Florida) a. Determine the coefficient of uniformity and the coefficient of gradation for Soils A, B, and C. b. Which one is coarser: Soil A or Soil C? Justify your answer. c. Although the soils are obtained from the same stockpile, why are the curves so different? (Hint: Comment on particle segregation and representative field sampling.) d. Determine the percentages of gravel, sand and fines according to Unified Soil Classification System.
Refer to Problem 2.C.1. Results of the sieve analysis for Soils A, B, and C are given below. To obtain a more representative sample for further geotechnical testing, a ternary blend is created by uniformly mixing 8000 kg of each soil. Answer the following questions. a. If a sieve analysis is conducted on the mixture using the same set of sieves as shown above, compute the mass retained (as a percentage) and cumulative percent passing in each sieve. b. What would be the uniformity coefficient (Cu) and the coefficient of gradation (Cc) of the mixture?
A hydrometer test has the following result: Gs = 2.65, temperature of water = 26 C, and L = 10.4 cm at 45 minutes after the start of sedimentation (see Figure 2.25). What is the diameter D of the smallest-size particles that have settled beyond the zone of measurement at that time (that is, t = 45 min)?
