Froude, Mach & Weber Numbers
Calculate the Froude, Mach and Weber numbers of a flow from velocity, length, density and surface tension, free online.
À propos de cette calculatrice
Froude Fr = v ÷ √(gL) compares inertia to gravity (ship waves, open channels); Mach Ma = v ÷ c compares speed to the speed of sound (343 m/s in air at 20 °C); Weber We = ρv²L ÷ σ compares inertia to surface tension (droplets, sprays).
