0000001599 00000 n How to Use a Zero Water Tester For Water Quality - Home Trendys 385 0 obj<>stream 0000065989 00000 n The procedure utilizes Stoke's Law of settling velocity for spherical particles in a fluid; 2 2 ( ) 9 2 = g D Vs f (1) where; hydrometer reading when taken at a different temperature than the hydrometer's calibrated temperature. The suction (pull) of soils does not depend on the ___________. Plotting. It was designed to allow a comparison between densities of petroleum liquids. Hydrometers can be divided into two general classes: those scaled for liquids heavier than water those and liquids lighter than water. The silt has settled to the bottom of the cylinder by this time. 0000066262 00000 n Pick - out the INCORRECT assumption of terzaghis theory of consolidation of soils. The candidates appliedbetween 14th September 2022 to 4th October 2022. 0000000016 00000 n (NOTE: 100 mL + 880 mL = 980 mL the missing 20 mL accounts for the approximate volume occupied by 50 grams of soil). How to guide: Hydrometers & Brineometers - The Laboratory People Readers with specific questions should refer to the applicable standards or consult with an attorney. You have to select the right answer to the question. %PDF-1.3 % 7.10 Record the hydrometer reading again after 6 hours, 52 minutes. Record the temperature of the soil-water suspension to the nearest 0.5C for each hydrometer reading. API-scale hydrometers measure of how light or heavy a petroleum-based liquid is compared to water. trailer A soil found naturally has a bulk density of 2 g/cc with 5% water content. Particle size distribution obtained from sieve analysis may be combined with the data from a hydrometer analysis to produce a complete gradation curve. PDF Method of Test for Mechanical Analysis of Soils With the help of an accurate scale, measure the height between the neck of the hydrometer to each of the other The hydrometer measures the specific gravity of the soil suspension at the center of its bulb. Learn more about how Pressbooks supports open publishing practices. The exam was conducted on 19th February 2023 for both Paper I and Paper II. 422 0 obj <> endobj 2 0 obj The hydrometer should be removed, rinsed and placed in the distilled water after each reading. 0000009845 00000 n Calculate the percentage of particles finer than D from the following formula 100 G, N = -X ( Rh +/- M t ) W s (G,1) GS =Specific gravity of soil particles.
