\begin{equation}
\left(\mathbf{v} \cdot \nabla \right)\mathbf{v} + \frac{1}{\rho}\nabla P + \nabla \Phi_G -\nu\left[\nabla^2\mathbf{v} + \frac{1}{3}\left(\nabla \cdot \mathbf{v} \right) \right] = 0
\end{equation}
where it is understoond that gravitational potential $\Phi_G$ and the coeficcient of kinematic viscosity $\nu$ are time independent. Now use the idenity $\left(\mathbf{v} \cdot \nabla \right)\mathbf{v} = \frac{1}{2}
\nabla\left\mathbf{v} \nabla \left( \mathbf{v} \cdot
\mathbf{v}\right) - \mathbf{v} \times \left( \nabla \times \mathbf{v}\right)$ Integrate the momentum equation for a steady, nonviscous, flow along a streamline
\begin{equation}
\int{\mathbf{ds}\cdot (\rm{momentum equation})}
\end{equation}
