Present investigation develops theory of continuous mechanics for formulation general laws of equilibrium as laws of equilibrium angular momentum. Besides influence of cross flux on description of continuous mechanics is discussed. Usually the equilibrium conditions for forces are postulated in spite of that it is special case interpretation. The new model for solution the problem of flow rarefied gas near bodies is suggested. Layer closed to surface is order of some radius of interaction molecules. The modified Navie-Stokes for remainder can be used and conjugate conditions at surface can be written without the Knudsen layer. You will be able to count friction and heat flow to the surface by solution the Boltzmann equation without collision integral in thin layer and by solution the Navie-Stokes equations with addition new terms. The Chapman-Enskog distribution function as boundary condition for external boundary of thin layer is used with macroscopic parameters are det
