With materials that have adensity other than 2.65, it will be necessary to correct for this in the calculations fortheoretical specific surface area, as well as in the actual specific surface area determination.(23) The following example illustrates the procedure for determining S th , S w and E.Example:Sample weight … … … 50 gVolume of <strong>Sand</strong> Bed … 30.6 cm 3Time … … … … … 22.8 sFrom the graph, Figure 1, the actual specific surface may be read directly in squarecentimetres per gram of sand.S w = 110.0 cm 2 /g.19
