The periodic pressure fluctuation with a very long period of around 5 minutes is observed in pressure measurements by a Pitot tube in a high speed rotating cylinder. The observed frequency is much lower than the rotational speed or calculated Karman vortex frequency. Theoretical analysis is also done in considering the fluid forces that act on a Pitot tube. Theoretical results show good agreement with the experimental ones. Consequently, the observed vibration is induced by hydrodynamic force which whirls the Pitot tube.
