AI Thread Summary
Iron core solenoids have specific proportional relationships between the coil width and the core diameter that affect their magnetic field properties. When the coil width exceeds the core diameter, the solenoid may experience magnetic saturation, leading to a drastic shift in performance. This saturation limits the solenoid's ability to generate a strong magnetic field, impacting its efficiency. Understanding these proportions is crucial for effective solenoid design. Further study on magnetic saturation and solenoid equations can provide deeper insights into these effects.

Hi, I've been trying to learn about iron core solenoids and I'm having trouble finding information on a concept (probably obvious but I'm new to this). I've been looking at the equations for iron core solenoids online, and it's alluded to that these equations only hold true when the proportion of the solenoid coil width isn't greater than the iron core diameter or something like that? Is this correct? Is there some "drastic shift" in the magnetic field properties that is going on when these proportions are exceeded? I'm hoping someone can enlighten me and point me in the right direction for further study.
Thanks

Yes, it is called magnetic saturation.
 

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...
