If the 10X peak is at 2500 CPM, what is the machine's running speed?

If the 10X peak is at 2500 CPM, what is the machine's running speed?

• A. 2500
• B. 25000
• C. 41.6
• D. 250

Answer: (D)

In vibration analysis, the concept of harmonics is essential when determining running speeds. The 10X peak indicates that the frequency measured is ten times the fundamental running speed of the machine. To find the machine's running speed, you divide the peak value by 10. In this scenario, with the 10X peak occurring at 2500 cycles per minute (CPM), the calculation would be: 2500 CPM ÷ 10 = 250 CPM. This result indicates that the machine is operating at a fundamental frequency of 250 CPM, which correlates to its running speed. The other choices, while numerically might seem reasonable, do not appropriately represent the calculation based on the information provided regarding the 10X harmonic.
