At about the same time as each soil suspension hydrometer reading, take a hydrometer Calculate the temperature correction for the hydrometer readings. Therefore hydrometer analysis is done for grain size analysis of fine grained soils. 2. Take 50 g of the minus 200 soil (Step 6) and run a hydrometer analysis. APPARATUS Glass measuring cylinders 2 nos of 1000 ml capacity with ground glass or rubber stoppers about 7 cm diameter and 33 cm high marked at 1000 ml volume. Koya University Faulty of Engineering School of Chemical&Petroleum Engineering Chemical Engineering department Laboratory of petroleum and gas properties EXPERIMENT NUMBER TWO Hydrometer Instructor: Mr. Abdulmajid & miss Cheeman Author Name: Aree Salah Tahir Experiment Contacted on: 22/oct/2013 Report Submitted on: 29/oct /2013 Group:A Volume of hydrometer 55 cm3 Area of cylinder 28.274 cm2 agent 0.002 g/cm3 T ref 22 0C H 1 16 cm H 2 6 cm 1 1.000 g/cm3 2 1.040 g/cm3 With these inputs, following procedure can be applied to do calculations of a single row in lab datasheet for a hydrometer reading 1.026 at time t = 120 sec (2 min. 1: Hydrometer. Using a sieve and hydrometer analysis, the viability and the use of a particular soil can be found. Record the mass of the air-dried sample as W A under Section 13. The stirring apparatus consists of an electric motor capable of … Sedimentation Analysis - Hydrometer Method ... We will need it for further calculations. The method is based on Stoke’s law governing the rate of sedimentation of particles suspended in water. Grain Size Analysis by Hydrometer 1. objective. The Day hydrometer method has a sound theoretical base and is widely accepted by soil laboratories as a reliable means of determining soil particle size distribution. HOW TO DO HYDROMETER ANALYSIS OF SOIL EQUIPMENT. You learned in the EA3 TRAMAN that a soil is considered susceptible to frost when it contains 3 percent or more by weight of particles smaller than 0.020 mm in diameter. Property of SFU Soil Science Lab Making Calculations: 1. Weight of oven dried soil in 6. Summary of Methods The hydrometer analysis is utilized for particle sizes finer than 75 μm. This video tutorial explains how to solve hydrometer problems in physics. The test is used in conjunction with a standard sieve analysis of fine-grained soils with a wide range of particle sizes to provide a complete gradation curve. 1. b. SA-1 Soil Hydrometer, ASTM 151H is graduated to read specific gravity. Dispersing agent 9. Take about 50g in case of clayey soil and 100g in case of sandy soil and weigh it correctly to 0.1g. The soil particles will settle individually A hydrometer analysis is the process by which fine-grained soils, silts and clays, are graded. Hydrometer Analysis of Soil, continued. Determine the volume of the hydrometer bulb, VR. The hydrometer test is performed by testing a soil sample that was allowed to pass through a number 10 sieve size. Particle Size Analysis Lab. The hydrometer analysis per ASTM D422 was conducted to determine the distribution of the finer soil particles of the soil sample. Specific gravity of the soil 5. 2.2 Balance: An AASHTO M-231, Class C balance for weighing the hydrometer analysis sample. 2.3 Stirring Apparatus: A mechanically operated stirring apparatus for mixing the soil slurry. (Follow steps 1 through 14 as described previously.) Theory: Hydrometer method is utilized for assessment fot the particle size circulation of fine-grained soils passing 75 sieve. Table 3 – Hydrometer Effective Depth Using Table 2 and Table 3 shown above, a hydrometer analysis can be performed as supplementary data for further behavior of the soil: Sample Calculations Introduction Grain size analysis, being one of the oldest tests, helps engineers determine the relative proportions of different grain sizes as they are distributed among certain size ranges. Hydrometer 1. Oven-dry wt. Adjusting hydrometer values: For each degree your sample is below the temperature at which Previous calculations show that the specific gravity is 2.22. 2. The procedure used followed ASTM standard D422, Standard Test Method for Particle-Size Analysis of Soils. Meniscus correction (Cm) = +0.5 11. Sieve analysis gives the intermediate dimension of a particle; hydrometer analysis gives the diameter of a sphere that would settle at the same rate as the soil particle. 4.Procedure 4.1 Calibration Of Hydrometer 1.Determination of volume of the hydrometer bulb (Vh): Pour about 800 ml of water in the 1000 ml measuring cylinder and note the reading at the water level. If it is not possible to take a 420 minute reading, take a substitute reading at the end of the day, noting the elapsed time. the soil. Temperature correction (Ct) 2. 1 Particle Size (Hydrometer) DATE: SEPT 2004 Particle Size Analysis (Hydrometer Method) 1. The hydrometer is re-inserted in the suspension and readings are taken after periods of 8, 15 and 30 minutes; 1, 2 and 4 hours after shaking. See Appendix B for blank hydrometer method. 9. reading); Density of fluid f [1] For assessment of the particle size distribution of soil by hydrometer method. The hydrometer computes the specific gravity of the soil … Grain Size Distribution Documentation of Calculations 4 1.3Hydrometer Test Calculations 1.3.1Particle Size PS = s 30 v L 980 (GS GW) ET (1.8) Where: Ps = the particle size in mm. Hydrometer test is carried out to quantitatively determine the Particle/Grain Size Distribution for soil particles of size smaller than 75 micron. The effective depth is found using the Hydrometer 151H table shown in figure 4. To determine whether or not a soil contains an excessive amount of that size particle, you must perform a particle-size analysis of the materials passing the No. Area of the jar 3. These particles pass through the last sieve (No. Hydrometer No. STANDARD IS: 2720 (Part 4) 1985. Specific Gravity Determination Apparatus 3. CALIBRATION OF THE HYDROMETER. Hence, after the sieve analysis test was conducted, calculations pertaining to it were summarized in Table 1 (Coduto, 2011). The percentages of gravel, sand, silt, and clay-size particles present in a soil can be obtained from the particle-size distribution curve. Correction for dispersing agent (Cd) 10. HYDROMETER ANALYSIS 1. The laboratory instructor will provide the percent moisture of the air-dry soil samples. The density of the soil-water suspension depends upon the concentration and specific gravity of the soil particles and the amount of dispersant added.
