    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!
 
Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter.
