  The Navier-Stokes equations are considered by the use of the method of
Lagrangians with covariant derivatives (MLCD) over spaces with affine
connections and metrics. It is shown that the Euler-Lagrange equations appear
as sufficient conditions for the existence of solutions of the Navier-Stokes
equations over (pseudo) Euclidean and (pseudo) Riemannian spaces without
torsion. By means of the corresponding (n-1)+ 1 projective formalism the
Navier-Stokes equations for radial and tangential accelerations are found.
