What is liquid volume fraction?
In chemistry, the volume fraction φi is defined as the volume of a constituent Vi divided by the volume of all constituents of the mixture V prior to mixing: Being dimensionless, its unit is 1; it is expressed as a number, e.g., 0.18.
What is solid volume fraction?
Volume fraction in solid materials science and engineering often refers to concentration of a given phase, that is, the ratio of volume of the given phase to total volume of the sample. Thus, the volume fraction is dimensionless.
Is mass fraction the same as volume fraction?
Pure water density is 1g/cm3, whereas your nanoparticles have a density different from 1. That is why weight fraction (solute mass/total mass) cannot be equivalent to volume fraction (solute volume/ total volume) because the equivalency between mass and volume in the solute is different from 1.
What is polymer volume fraction?
description. In liquid: Volume fraction. ) The composition of a nonelectrolyte solution containing very large molecules, known as polymers, is most conveniently expressed by the volume fraction (Φ)—i.e., the volume of polymer used to prepare the solution divided by the sum of that volume of polymer and the volume…
What is nanoparticle volume fraction?
The nanoparticle volume fraction in the presence suction has a significant effect on temperature field. In the presence of suction, it is also observed that the rate of heat transfer of SWCNTs–water first decreases and then increases with increase of nanoparticle volume fraction, Table 5.
What is gas volume fraction?
GVF – Gas volume fraction is the ratio of the gas volumetric flow rate to the total volumetric flow rate. LVF – Liquid volume fraction is the ratio of the liquid volumetric flow rate to the total volumetric flow rate. Void fraction is the ratio of the flow area occupied by the gas to the total flow area.
How do you convert volume fractions to mass fractions?
m(O2)/V(total) = (209.5+x)*32/(Vm*1). Here x= is volume of oxygen added, x(cm^3)=1*t ((cm^3/min)*min), t(min) is time during which oxygen was added, 32 is molar mass of O2, Vm is molar volume, 1 = 1litre, volume of your chamber.
What is volume fraction in composites?
Fiber volume ratio, or fiber volume fraction, is the percentage of fiber volume in the entire volume of a fiber-reinforced composite material. When manufacturing polymer composites, fibers are impregnated with resin. A higher fiber volume fraction typically results in better mechanical properties of the composite.
