Shaft Speed

AI Thread Summary

The critical speed of a shaft supported at its ends by bearings can be determined without load by analyzing the natural frequency of the system. The effects of critical speed include potential resonance, which can lead to excessive vibrations and structural damage. Dunkerley's method is often referenced for calculating critical speed, taking into account factors like shaft length and mass distribution. Understanding these dynamics is crucial for ensuring operational stability and longevity of rotating machinery. Proper assessment of critical speed helps in designing effective support systems for shafts.

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
