Pitot Tube Velocity Calculator — Formule
## Pitot Tube
A pitot tube measures airspeed by comparing stagnation (total) and static pressure.
### Formula
**v = sqrt(2 (P_total - P_static) / rho)**
where the difference (P_total - P_static) is the dynamic pressure q = 0.5 rho v^2.
Pitot tubes are standard instruments on aircraft for measuring airspeed.

Exemple Résolu
Aircraft: P_total = 102 000 Pa, P_static = 101 325 Pa, rho = 1.225 kg/m3.
- dP = 102000 - 101325 = 675 Pa
- v = sqrt(2 * 675 / 1.225)
- v = sqrt(1102)
- v = 33.2 m/s = 119.5 km/h
