The problems of the gas as a environment with a moving border of division of phases are considered.  Defined initial and border conditions of  Laplace’s equation for unsteady flow density in the moving coordinate system.  Based on this equation is given of the general solution of the problem.  Equation is solved analytically for the density of the gas flow at a total initial and border conditions. The final result is obtained by converting the equation except for members who have little weight in this equation. The analysis shows that the additional resistance arises in any case that can compensate for the right balance of the pipe length – diameter of the pipe.
