# Eulers equation of motion - Formula - Fluid Mechanics

**Q. What is the correct formula for Euler's equation of motion?**

Where,

ρ = density of the fluid

p = pressure force

g = acceleration due to gravity

v = velocity of the fluid*- Published on 04 Aug 15***a.** (∂p / ρ) + (∂g / ρ) + (∂v / ρ) = 0

**b.** (∂p / ρ) + (∂g / ρ) + (v dv) = 0

**c.** (∂p / ρ) + (g dz) + (v dv) = 0

**d.** (p dp) + (g dz) + (v dv) = 0

**ANSWER: (∂p / ρ) + (g dz) + (v dv) = 0**
