**Formula**

**Euler Number :**

Eu = Δp/ ρV^{2}

**Pressure Change :**

Δp= EuρV^{2}

**Density :**

ρ = Δp/ EuV^{2}

**Characteristic Velocity :**

V =√ Δp/ Euρ

**Where,**

Eu = Euler Number,

Δp = Pressure Change,

ρ = Density,

V = Characteristic Velocity.

This advanced online Euler Numbers Calculator is used to calculate and fins the Euler Number, Pressure Change, Density and Characteristic Velocity.

__Example__:

Calculate the Euler Number for the given details.

Pressure Change (Δp) = 25 P

Density (ρ) = 15 kg/m^{3}

Characteristic Velocity (V) = 5 m/s

__Solution__:

**Apply Formula:**

Eu = Δp/ρV^{2}

**Euler Number (Eu) =** **0.07**
