Calculate the time needed to fill a compressor

Click For Summary
SUMMARY

Koniako seeks assistance in calculating the time required to fill a helium compressor with a volume of 2m3 of gaseous helium at room temperature (293K) and pressure (1.013 bar). The filling procedure is estimated to take one hour, with a pressure differential (Δp) of 500 mbar over a distance of 10-15 meters. The discussion focuses on determining the appropriate method for sizing the filling pipe to accommodate these specifications.

PREREQUISITES
  • Understanding of gas laws and behavior, specifically relating to helium.
  • Knowledge of fluid dynamics and pressure differentials.
  • Familiarity with pipe sizing calculations and flow rates.
  • Basic principles of thermodynamics, particularly at room temperature conditions.
NEXT STEPS
  • Research "Gas flow rate calculations for compressible fluids" to understand how to calculate flow rates for helium.
  • Study "Bernoulli's equation and its application in pipe flow" to apply fluid dynamics principles effectively.
  • Learn about "Sizing pipes for gas transport" to determine the correct diameter for the filling pipe.
  • Investigate "Pressure drop calculations in piping systems" to ensure the system operates within the specified Δp limits.
USEFUL FOR

Engineers, technicians, and professionals involved in gas handling, compressor design, and fluid dynamics will benefit from this discussion.

Dear all,

I would like to have your help for a problem that i face. I know that it is a little bit ridiculous, but my brain is stacked right now!

I have a helium compressor that i want to fill it with helium at room temperature 293K @ 1.013bar. This compressor will be connected with a pipe. As i want to size the pipe i assume that the filling procedure takes about an hour. I have available 500mbar of Δp for a distance of 10-15 meters.

Which method should i follow?

Thanks everybody in advance,
Regards
Koniako

It's not clear what you are trying to do.

Are you talking about filling a receiver (a tank) with helium gas?
 
Hi steamking,

thanks for your answer..
I am trying to size the pipe for filling my compressor. The mass of the compressor that i have to fill is 2m3 of gaseous helium and i try to calculate the size of the line..! I am sorry if i didn't explain better..!

Thanks again...
Koniako
