Which of these equations represents non – dimensionalize continuity equation?

A. ∂\(\frac {(\overline {ρ} \, \overline {u})}{∂\overline {x}}\) + ∂\(\frac {(\overline {ρ} \, \overline {v})}{∂\overline {y}}\) + ∂\(\frac {(\overline {ρ} \, \overline {w})}{∂\overline {z}}\) = 0
B. ρ u\(\frac {∂ \overline {u}}{∂\overline {x}}\) + ρ u \(\frac {∂ \overline {v}}{∂\overline {y}}\) + ρ u \(\frac {∂ \overline {w}}{∂\overline {z}}\) = 0
C. ρ u\(\frac {∂ \overline {u}}{∂\overline {x}}\) + ρ u \(\frac {∂ \overline {v}}{∂\overline {y}}\) + ρ u \(\frac {∂ \overline {w}}{∂\overline {z}}\) = –\(\frac {∂ \overline {p}}{∂\overline {x}}\)
D. ρ u\(\frac {∂ \overline {u}}{∂\overline {x}}\) + ρ u \(\frac {∂ \overline {v}}{∂\overline {y}}\) + ρ u \(\frac {∂ \overline {w}}{∂\overline {z}}\) = –\(\frac {∂ \overline {p}}{∂y}\)
Answer» B. ρ u\(\frac {∂ \overline {u}}{∂\overline {x}}\) + ρ u \(\frac {∂ \overline {v}}{∂\overline {y}}\) + ρ u \(\frac {∂ \overline {w}}{∂\overline {z}}\) = 0
