## Homework Statement

Question Details:

The question reads:

Show that the equation:

dA/A + dv/v + dρ/ρ = 0

applies to a one-dimensional steady flow. (Here 'one dimensional' means that both the density ρ and seed v = - v . n (vectors) are constant across any cross-sectional area A cutting the flow.)

Please help!

## Homework Equations

d/dt ∫

_{V}ρ dV + ∫

_{A}-ρv⋅n dA = 0

## The Attempt at a Solution

I know that the equation they gave us above is the differential equation for ρ*v*A = constant, I just don't know where to go from there.
