Calcolatore Resistenza Indotta — Formula

Dynamic Pressure

Dynamic pressure represents the kinetic energy per unit volume of a flowing fluid. It is the key scaling parameter for aerodynamic forces.

Formula

q = 0.5 × rho × V²

where rho is the fluid density and V is the freestream velocity. All aerodynamic forces (lift, drag) are proportional to dynamic pressure, which is why it appears in every force coefficient definition.

Esempio Risolto

Air at sea-level standard density flowing at 100 m/s.

  1. q = 0.5 × 1.225 × 100²
  2. q = 0.5 × 1.225 × 10000
  3. q = 6125 Pa = 6.125 kPa
