Running Head: LAB 1. DETERMINATION OF WATER CONTENT AND SPECIFIC GRAVITY OFSOLID SOILS1Lab 1. Determination of water content and Specific Gravity of Solid SoilsNameGroup NumberDateDetermination of water content and Specific Gravity of Solid Soils2IntroductionPurpose of the experimentThe purpose of this experiment is to determine the water content and the specific density of a soilsample.Background InformationThe water content of a soil sample is the amount of water the sample contains. The water contentis measured as the ratio of the mass of water contained in the soil to the mass of the dry soil. Thewater content is an important parameter in studying hydrology, stream flow, irrigation and cropproduction.water content=(mass of water present in soil sample)/(mass of dry soil sample)The specific density of a substance is defined as the ratio of the density of the substance to thedensity of water at a specific temperature. The specific density can, therefore, be defined as theratio of the mass of the substance to the mass of an equal volume of water. The specific density isa ratio and therefore is a dimensionless quantity in that it does not have units. In the case of soil,its specific density is the ratio of the density of solely the solid phase of the soil, excluding theliquid and air phases to the density of water. The specific density of soil is an important quantityin the determination of the relationship between the various phases of the soil. ...
