3 PERCENT PSSING CLCULTION (RIZ 201) To calculate percent passing you will need a scientific calculator with at least one memory. lways add up all the weights, never change the amount in the total box. If the calculated total is 1.0% or less from the total in the total box, adjust the number of the sieve weight with the largest amount retained, except for the passing #4. CORSE SIEVE a. To get the Coarse sieve factor, divide 100 by the total weight of sample (the number in the total box). b. Place the factor in the memory of the calculator (MR+). c. Enter 100 in the calculator, subtract the first weight retained, times (x) the factor (memory recall) (MR),then the key this will give you the % passing that sieve. d: Keeping that number in the calculator subtract the next weight retained, multiply it by the factor (MR) until all % passing is calculated and recorded. e. Continue this down to the #4 weight retained. f. Then do a check on the pass #4 by, multiplying the weight passing the #4 times the factor (MR). FINE SIEVE lways add up all the weights, never change the amount in the total box. If the calculated total is 1.0% or less from the total in the total box, adjust the number of the sieve weight with the largest amount retained except, for the passing #200. a. Subtract the Total Dry Weight from the Dry Wt. of -#4 Split weight to get the elutriation weight and record it in the box provided. b. To get the fine sieve factor, take the % passing the #4 (whole number) and divide it by the adjusted split weight. c. Place the factor in the memory of the calculator. d. Enter the % pass the #4 (whole number) in the calculator, subtract the weight retained on the #8 sieve, multiply, (x) it by the factor (MR) to get the % passing the #8. e. Keeping that number in the calculator subtract the next weight retained (#10), multiply (x) it by the factor (MR) until all % passing is calculated and recorded. f. Continue this procedure down to the #200. g. Do a check on the pass #200 by multiplying the (weight passing the 200 sieve plus + the elutriation weight) by the factor (MR). When all the percent pass results are recorded, you may now record the percent retained for each sieve. Start with the largest % pass and subtract the next smaller % pass from it. Continue this down to the #200 sieve(rounded).
