Line 17:
: <math>\frac{\mathrm{d}}{\mathrm{d}t}\int\limits_{V_f} \rho(\vec x, t) \, \mathrm{d}\Omega = 0</math>
Applying the [[Reynolds transport theorem]], one can change the reference to an arbitrary (non-fluid) [[control volume]] <var>V<sub>c</sub></var>. Further assuming that the [[density|density function]] is continuous (i.e. that our fluid is monophasic and
