Exceptional Organisations & Leadership Awards Explains that the hydrometer test covers the quantitative determination of the particle size distribution in a soil from coarse sand size to clay size. Visually, the best-fit line on the graph was more accurate with a 5th order equation. It represents the relationship between water/moisture content and dry density. We know that nearly any mechanical compactive effort will make soil denser, but which methods work best for each soil type? Most importantly, how does the maximum soil density that we find in our laboratory tests relate to the soil densities we find in the field? The data collected from this lab refutes this hypothesis because the results were unexpected. Maximum Velocity of the enzyme-inhibited reaction, Vmax. Substrate Concentration, S. X-axis of the Lineweaver Burk plot that is reciprocal of substrate concentration, [1/S]. The following graph should result. This straight line is called a ZERO AIR VOID LINE. Explains that sieve analysis demonstrates that almost of soil consisted of sand, and very limited clay. What it comes down to is it doesn't matter where you plot your air voids line from 0%(well above proctor) to 5%+(well below proctor), the crucial point is that the wet side of the proctor curve should be close to parallel with the air voids line. If you work through the instructions with our demonstration workbook file, undo each solution before you start the next. I tried to use IF(And(. but that didn't work. If you turn on data labels, you will see the zero listed. I need to figure out a way not to plot those errors and zeros. We have received your request and will respond promptly.
