    Seal Temperature
AI Thread Summary
To calculate the temperature of a seal using known variables like RPM, pressure, time, and coefficient of friction, one can start by determining the frictional force between the seal and the shaft. The frictional force multiplied by distance gives the work done, which translates to heat generated. This heat must be dissipated, and the method of heat rejection—whether through conduction, convection, or a fluid flow—needs to be considered. Understanding these principles allows for an estimation of the seal's temperature. This approach provides a foundational framework for the calculation.

Is there an formula to calculate temperature on a seal if rpm, pressure, time and coefficient of friction are known? Thank you.

Sincerely

Hi tall one. You can apply basic principals here. Do you know how to determine frictional force between the seal and shaft? Frictional force times distance is work. Work per unit time is power (ie: heat which must be dissipated). Once you have heat load, you need to figure out how that heat is being rejected. Either through simple conduction or convection or perhaps there's a fluid that's flowing past the seal that can carry that heat away. Hope that helps.
 
Thanks! I'll give it try.

BTW - this site is cool!
 

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...
