foulness Properties Practical - Essay ExampleThere are different and diverse characteristics of basis (1) Particle Size, (2) loudness Density, (3) Consistence, (4) Texture and (5) Water-holding Capacity. This lab allow for concentrate in determining 4 different types of solid from the 4 samples provided using the mechanical analysis technique. This technique is founded on the concept that different sizes of reproach particles fall kayoed of suspension at different speeds. Mechanical analysis of the texture of soil places a mixture of soil and water in a glass cylinder which is shaken to the point where suspension particles appear. These suspension particles step by step settle to the bottom of the cylinder once placed on a flat surface and is undisturbed. harmonise to Stokes Law, different sizes of particles fall out of suspension at different speeds. These speeds are clearly defined by this law. This law fundamentally states that larger particles will t decision to settle fast er out of suspension as opposed to smaller particles. Therefore, due to the fact that sand particles are larger than clay or silt, they will tend to form a distinct layer at the bottom once its settles out of suspension. This manner uses a hydrometer.Step 3 Added 5 ml of a dilute Calgon solution. The Calgon was to help disperse the soil particles so that they would fall independently of each other. This is necessary because this is a fundamental assumption of Stokes law.Step 4 Filled the blender cup with distilled water so the top of the suspension is about 10 cm from the top. Placed the top on the blender and blend for about 5 minutes. This step is designed to well disperse the soil particles.Step 7 Placed a rubber stopper over the end of the cylinder and re-suspended the mixture by turning the cylinder end to end several times vigorously. past set the cylinder back down and recorded the exact time (to the second).Step 8 directly after setting the cylinder down, carefully inser ted the hydrometer into
