Amount of fluid mass passing through a certain area per unit time:
\dot m_A = \frac{d m}{ d t} \Big|_A = j_m \cdot A |
where
| mass flux |
| SI unit | Metric unit | Oilfield units |
|---|---|---|
| kg/s | kg/s | lb/s |
Mass flowrate is related to volumetric flowrate and fluid density
as:
\dot m_A = \rho \cdot q_A |
