  6. Mass flux - Wikipedia

    en.wikipedia.org/wiki/Mass_flux

    Mass flux. In physics and engineering, mass flux is the rate of mass flow per unit of area. Its SI units are kg m −2 s −1. The common symbols are j, J, q, Q, φ, or Φ ( Greek lowercase or capital Phi ), sometimes with subscript m to indicate mass is the flowing quantity. Mass flux can also refer to an alternate form of flux in Fick's law ...
