TO THE IDENTIFICATION OF THE SELF-OSCILLATING PERIOD
OF THE LIQUID LEVEL AT THE SIPHON DISCHARGING
It is considered period of relaxation self-oscillations in hydraulic system known as “tantalum container”
which consist of vessel with a constant inflow and outflow through a siphon. The emptying time of the vessel
through the siphon is taken into account. More accurate formula for the period of self-oscillations is derived.
Curves for error estimation at neglect of the emptying time of the vessel is pointed.
Keywords: vessel with a constant inflow and outflow through a siphon, self-oscillating system of
accumulating type, siphon discharging coefficient, time of filling of the siphon ascending branch, the
emptying time of the vessel through the siphon, self-oscillating period of liquid level in a vessel.
