Assumption: in a water / HC mixture, mass fraction is the same as volume fraction.

Assumption: in a water / HC mixture, mass fraction is the same as volume fraction. Example 1: 99 kg HC (density 700 kg/m3) and 1 kg H2O (density 1000 kg/m3). Mass fraction of H2O = 1/(99+1) = 1% Vol of HC = 99/700 = 0.14143 m3 Vol of H20 = 1/1000 = 0.001 m3
