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 units
