  The paper is devoted to a detailed analysis of the two important transport
processes - the kinematic shear viscosity and the self-diffusion - for all
states of liquid water from the triple point to the critical point. Our
approach to the shear viscosity is grounded on friction effects between the two
nearest molecular layers shifting relative to each other. In this relation, the
nature of the shear viscosity in water is fully similar to that in argon. The
contribution, caused by interlayer displacements of molecules, is assumed to be
negligibly small. The behavior of the kinematic shear viscosities of water is
investigated in detail in the two characteristic directions: the vapor-liquid
coexistence curve and isotherms. As for argon, it is assumed that the
self-diffusion in water is formed by the two main contributions, caused by the
molecular transport by nano-scale vortex hydrodynamic modes and collective
intermixing of molecules on molecular scales. The mechanism of the second type
is with good accuracy described by the Einstein formula with a hard-core radius
of a molecule determined from analysis of the shear viscosity of water.
