The larger the tank, and the greater its height (and thus its potential velocity), the greater the water's capacity to create an impact when a valve is opened and the water (like electrons) can flow. Why measuring voltage is useful Technicians approach most troubleshooting situations knowing ...
aIf rms velocity fluctuations are on the order of 5% of the mean speed they show that density fluctuations are unimportant up to Mach numbers around 3 t0 5. 如果rms速度波动是大约5%平均速度他们表示,密度波动是不重要的由马赫数决定在3 t0 5附近。 [translate] a欢迎发表观点或输入您需要翻译的文本...
peak amplitude, crest factor, skewness, root mean square (RMS), etc.) of the signal directly from the time waveform. This technique is useful for detecting transient phenomena like impacts or shocks.

Oil whip is related to the shaft stiffness which has an eccentric structural resonance frequency not following the rotational speed. Due to the oil flow velocity, whirl is indicated by vibrations at a sub-harmonic order component between 0.42-0.48 order of the shaft rotation. Oil whirl starts ...
A directional quantity that also has some magnitude is called a vector quantity. The representation of vector is done by a line with an arrow in the direction of the vector. Velocity and acceleration are examples of a vector quantity.
The similarity may in fact be part the reason that students of electrical or mechanical engineering often find the others’ studies arcane and inscrutable; “v” means “voltage” to an electrical engineer (EE), but “velocity” to a mechanical engineer (ME), whose representations of springs ...
Different sensors are used in condition monitoring and range from displacement transducers to accelerometers, shock-pulse transducers, and velocity transducers. Each of them fits the purpose they have been developed for. The main difference is the accuracy they offer in a specific frequency range: ...
