Piping loss with air-turbocharger
Piping loss with air-turbocharger
(OP)
Air at 1000 CFM 80 degrees, sea level, enters a turbocharger for compression. Exits the compressor at 500 F, 32 psig, enroute to the CAC.
What is the air pressure loss for 4 feet (one sweep 90) of:
1.75" id pipe
2.5" id pipe
Thanks all.

Is the sweep 4' long? If not, what's r/d?
Good luck,

2.5" id pipe: dP = 1.02 psi.

Can you give me an idea how you did the calc, or which tables you used.
FYI, this is a turbocharger application. What you are saying is that the turbo would have to work to produce 15.9 psi, just to get the compressed product through this pipe.
(BTW this pipe leades to the charge air cooler, where the charge is air-air cooled to 180 degrees.)

The spreadsheet is based on adiabatic compressible flow equations in Shapiro's "The Dynamics And Thermodynamics of Compressible Fluid FLow".

Or if someone else can point me in the right direction to "learn how to fish" I would be grateful.

Spent the last decade and a half doing everything but CN work.
Your tips have saved me a lot of time. Guess it is now time to reaquaint myself with these old books.
Thanks again
