Volume of fluid passing through a certain area per unit time:
q_A = \frac{d V_A}{ d t} |
| SI unit | Metric unit | Oilfield units |
|---|---|---|
| m3/s | cmd = m3/d | bpd |
In Petroleum Industry this term depends on context and may mean pipeline flowrate or wellbore flowrate which can be measured at separator (and called Surface flowrate) or downhole (and called Sandface flowrate).
Volumetric flowrate is related to mass flowrate
and fluid density
as:
\dot m_A = \rho \cdot q_A |
