How to calculate speed: blade tips and more

Sep 23, 2013· Miles per hour, or mph in North America, is the most common unit. The equation looks like this: S = d/t. To find tip speed, we need the rotor diameter and rotational rate. So assume a rotor diameter of 100m and a rotation rate (ω) of 15 revolutions/min, rpm. Distance in this case is the circumference C of the rotor's circle, which is found

Failure Analysis Of Machine Shafts

Jul 16, 2012· For a fatigue failure to occur, the forces must have been applied many times. There are low-cycle failures but most industrial fatigue failures we've seen involve more than 1,000,000 load cycles. A valuable feature of fatigue-failure interpretation is that the crack growth, i.e., the surface appearance, tells how the load was applied.

Battling Fab Cycle Times

Feb 16, 2017· A simple way to look at cycle time is to apply a probability theory called Little's Law in the fab. In this case, cycle time equals work-in-process (WIP) over the start rate, according to KLA-Tencor. For example, if a fab has 12,000 lots, and it processes 4,000 lots per month, the total cycle time is 3 months, according to KLA-Tencor.
