2.6 Repeat Problem 2.3 with the following data: Mass of soil retained U.S. sieve no. on each sieve (g) 4 6. 0. 10

SG is 2.66 and temperature is 18 degrees celcius

Determine: 1. The percent finer in Sieve # 20  2. The percent finer in Sieve # 80  3. D60from the grain-size distribution curve  4. D30from the grain-size distribution curve  5. D10from the grain-size distribution curve  6. The coefficient of gradation  7. The uniformity coefficient  Please answer this asap. For upvote. Thank you very much
