Consideration has been given to the theory of oscillating 
flows in a pipe for the case where turbulence develops monotonically, 
reaching the pipe axis within a certain period of time after the beginning 
of acceleration. A mathematical model describing resonance oscillations 
of this type in an open pipe and consistent with experiment has been 
constructed.
