It affects the strength and load-bearing properties of rocks and soils. Disadvantages: sample must be dispersed in a liquid medium... some particles may (partially or fully) dissolve in the medium altering the size distribution. Range analysis is suitable when a particular ideal mid-range particle size is being sought, while cumulative analysis is used where the amount of "under-size" or "over-size" must be controlled. The size charts listed below are free to download and edit in many formats including pdf, ppt and word. In these systems, the scrubbing liquid (usually water) comes into contact with a gas stream containing dust particles. Particle size distribution can greatly affect the efficiency of any collection device. An example of this is the Coulter counter, which measures the momentary changes in the conductivity of a liquid passing through an orifice that take place when individual non-conducting particles pass through. A very fine sieve, such as 37 μm sieve, is exceedingly fragile, and it is very difficult to get material to pass through it. This value is determined mathematically by the equation: The value of σg determines the slope of the least-squares regression curve. �^��$�I$��N�Գ 8��X�â~f��Q>��ևtޓ�}g�6��� Y���k���_Yz�����śv�� Y�?�����C�8I���/�+���C� lk�J*>����U����=��j�>���J��Uz�@��o���L����O�c᰿�`�h�е�?t���2� �WלV�~�4s���~��f_�~;�][�w��G�\�Q�=S���uK�����Z��ޝ�����q�ų�nai�P�E]���^��$�K��K���K���5^Z�"|W��9!-���)y��� �|�)�)G)���Ց�;k�`NJ�(I"@H4��|��I��I�/���^��$�JF���R��$���Ր;� '�?眤�$5NA����RR�����?���^v�����&x��=���O�P�$�$�Jq����#U��B�I2IH� �)�I��Ր�;i�c��i% �H��IH��a$� �AG�~w_��Ր�;i����#�()%��(��IL�ZA� ����Ցį���)��% %!
