Coefficients Expansion Loss

AI Thread Summary

The discussion focuses on calculating an equivalent loss coefficient for a manifold with varying geometries. The main question is whether the loss coefficients from different area sections can be summed to determine a total loss coefficient. Participants are encouraged to provide insights or methods for accurately combining these coefficients. The inquiry references a specific equation, suggesting a technical approach to the problem. Overall, the thread seeks clarity on the summation of sudden expansion loss coefficients in fluid dynamics.

I was wondering since I'm trying to figure out an equivalent loss coefficient for a manifold that has a specific geometry. I have several area sections and would like to know if I can just add up the resulting loss coefficients from one section to the other.

Any help would be greatly appreciated.

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
