Mass Flow from Density
m_dot = ρ·A·v
What it says
The mass of fluid crossing a section each second.
Symbols
| Symbol | Quantity | Dimension |
|---|---|---|
m_dot | Mass flow rate (kg/s) | M T^-1 |
ρ | Density (kg/m^3) | M L^-3 |
A | Cross-sectional area (m^2) | L^2 |
v | Flow speed (m/s) | L T^-1 |
Work it out
Enter what you know. No account needed.
Fill in all but one: ρ, A, v, m_dot are all empty.
