mass-average velocity

Also contains definition of: molar average velocity in electrolytes

in electrolytes
Mass-average velocity:
v b = ρ −1 ∑ C i M i v i
Cf. molar average velocity:
v m = c t −1 ∑ c i v i
with c t = ∑ c i where M i = molar mass, c t = total concentration (mol m −1),ρ = density of the solution (kg m −3).
