Formula

u = p / (ρ·c).

How to Use

  1. Enter pressure, density and speed of sound.
  2. It returns particle velocity.

Case Studies

p=0.632, ρ=1.2, c=343 → u≈1.54e-3 m/s

u = 0.632/(1.2·343) ≈ 1.536e-3 m/s.

FAQ

Relation to pressure?

u = p/Z, Z=ρc is characteristic impedance (air ≈ 413 Pa·s/m).
