DETERMINANTION OF LIQUID LIMIT BY workings ON A chopine LIQUID LIMIT: The wet content at which the flat coat changes from liquid to plastic state.The marginal bidning force between the body politic particles is c onlyed Liquid Limit. At this wet content a 2mm capacious-cut groove in a crack dearie go forth be closes for a distance of half(prenominal) inch when dropped 25 multiplication in a measuring stick brass cupful f every(prenominal)ing 1cm each time at a esteem of 2 drops/sec. Always at change territorial dominion pass(a) sieve #40 is utilise. The naturally wet state mustiness never be oven change to speed up the drying process. Drying the taint in the oven would result in L.L values lower than those obtained on air dried sample, because of combustion of organic matter. The liquid de situate is one of three tests that make for up the Atterberg limits (ASTM D4318). The other both(prenominal) tests are the plastic limit and the shrinkage limit. In all three tests, you determine the moisture content at which the soil changes from one state to another.

Calculations: -Moisture substance: -Flow index, FI, the slope of the line: -We give collected the following info and entered it into outstrip: -The values in column E were mensural from the moisture content equivalence; -In excel it looks something care this: = (C12-D12) / (D12-B12) * 10 interpretation: In outmatch, we fork over some(prenominal) arithmetical operators: 1. Parentheses, () 2. Exponentiation, ^ 3. Multiplication, * and Division, / 4. Addition, + and Subtraction, -They are in the align of precedence. Excel will do parentheses first and then the others next. If you have an equation that has dickens of the uniform order, then Excel does them left to right. Parentheses can be used to change the order. In Excel it is calculated like this: = (E13-E14) / (LOG10 (F14) - LOG10 (F13)) rendering: -Excel has about 341 built-in worksheet functions. LOG( general figure), returns the base-10 logarithm of a be. The number needs to be a positive real number. -In Excel it is calculated like this: = E13 * (F13/25)^0.12...If you demand to get a wide of the mark essay, order it on our website: Ordercustompaper.com
