Friction Coefficient: How to Determine for Journal Bearing

AI Thread Summary
To determine the friction coefficient for a journal bearing, Petroff's equation can be utilized if sufficient parameters are known. If the necessary data is unavailable, consulting the textbook "Fundamentals of Machine Component Design" by Juvinall may provide further insights. Understanding the specific characteristics of the bearing is crucial for accurate calculations. The discussion emphasizes the importance of having the right parameters to apply the appropriate formulas. This approach will aid in effectively determining the friction coefficient.

Err.. what do u already know about this bearing? If u know enough parameter I suppose you could use Petroff's equation to find the coefficient of friction?

If can't then I'm not too sure about it too, perhaps have a look at the textbook "Fundamentals of Machine Component Design" by Juvinall ?

Hope this helps

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...
