Navier-Stokes equations general vector form

For a steady, inviscid flow along a streamline, show that the general vector form of the Navier-Stokes equations reduces to the familiar Bernoulli equation ... 

Consider the behavior of the Navier-Stokes equations for the two-dimensional flow in a conical channel as illustrated by Fig. 3.17. Begin with the constant-viscosity Navier-Stokes equations written in the general vector form as... 

The purpose of this appendix is to spell out explicitly the Navier-Stokes and mass-continuity equations in different coordinate systems. Although the equations can be expanded from the general vector forms, dealing with the stress tensor T usually makes the expansion tedious. Expansion of the scalar equations (e.g., species or energy) are much less trouble. 

The general form of the Navier-Stokes equation was discussed in a previous chapter. In vector notation, it can be shown as in Eq. 4.42 ...
