Question
In a hydrometer test, the results are as follows: Gs = 2.60, temperature of water = 24°C, R = 43 (K= 0.0132, L =9.2 cm) at 60 mins after the start of sedimentation. What is the diameter D, of the smallest-size particles that have settled beyond the zone of measurement at that time (that is, t = 60 min.)?

- Consider that a 58.7 gram sample of dry soil is used in making a mechanical analysis by using the hydrometer method. The laboratory was held at a constant temperature of 20 C (68 F). The 40 s hydrometer reading was found to be 32.5 and the 8 hr hydrometer reading was 15.5. The percentage of sand in this soil sample is (note, a 58.7 gram sample is used here): Your Answer: Answer unitsarrow_forwardA carefully-weighed 52.9 gram soil sample was dispersed for particle-size analysis using the Bouyoucos hydrometer method.
