The impact of rainfall drops on the soil surface can break down soil aggregates as the impact of falling raindrops breaks up the topsoil.

Multicomponent distillation 1) Mass balances The feed flowrate is 350 kmols hr-1 and the feed composition is known: 48 mol% propene‚ 50 mol% propane and 2 mol% butane. The distillate stream composition: 99.9 mol% propene and 0.1 mol% propane. The bottom product stream contains 0.5 mol% propene but the mole fractions of propane and butane are unknown. Therefore‚ mass balances are carried out around the distillate column. Overall mass balance: F=D+B Component mass balance for propene: xFF=yDD+xBB

Introduction The consistency of the soil is important information in the field of engineering. It determines the behavior of the soil when it suffers stress and strain. The degree of consistency of soil can do considerable influence on the water regime in the same‚ affecting the hydraulic conductivity for example. The consistency of a soil refers to the degree of strength and plasticity of the soil that depend on the internal links between the particles. Cohesive soils have plastic consistency between specific
