STABILITY OF А CURVED PIPE OUTLINED ON AN ARC OF CIRCLE
D. Lolov Sv. Lilkova-Markova The stability of plane pipe, conveying fluid and outlined on a circle is investigated in three cases of supporting. The fluid is heavy and non-compressible. Its velocity is constant. The influence of the deformation of a pipe in its axis is considered. The relation between the critical velocity of the fluid and the central angle of the pipe is obtained.
