11. Flow Induced Vibration Criteria For lines with theflow-induced vibrationsusceptibility as high, the pipe support span is reduced to increase the natural frequency of the piping system so that the tendency of FIV failure is reduced. Fig. 1: Figure showing pipe support span C. Deciding Pipe ...

If the source of the EMF is removed, then the inductor will create a back EMF to try to maintain the current. If an alternating signal is applied, then it will impede the flow of current as a result of the inductive reactance.The basic parameters are used within the inductor, whatever ...
The acquired data is sent to a computer and analyzed with Order Analysis software. Example of Order analysis results of a running machine. Left figure: a spectrogram of vibration values for the first 10 harmonic orders, measured between 1000 rpm and 3000 rpm. Right figure: extracted values for...
In simple words, a large mass of oscillating airflow can cause vibration of the turbo compressor impeller and its vanes, making the compressor unable to operate normally. As a reaction, this produces a high-pitched noise, which is known as compressor surge. ...

is observed. For a specific temperature and pressure condition, the orifice area at the outlet determines the volumetric flow rate of the fluid inside the pipe.Due to the high-pressure drop at the restriction orifices, it can createacoustic-induced vibration. Hence, studies must be performed by...
