Calculation
q = ½ · ρ · v²
Dynamic pressure rises with speed squared and underpins many loss models.

Result
Select a target and calculate.
Understand the inputs
- Dynamic pressure q — Velocity pressure relative to static pressure.
- Density ρ — Fluid density.
- Flow velocity v — Mean cross-section velocity.
Example
Water at 1 m/s: q = 500 Pa.
Assumptions and limits
Incompressible flow; local velocity profiles are averaged.
