Hi, I've been searching all around the net and I found this site. I was sure surprised to see there were ammonia people on it.
Anyhow, I am looking for a good chart or calculator to determine mass flow rate of ammonia vapor through various pipe sizes.
I have the IIAR Ammonia Refrigeration Piping Handbook but it only lists two higher pressures for flow rates (I'm looking for lbs/minute).
And, since I'm asking, if anybody can suggest a method for determining how much water can be delivered through various pipe sizes that would be very helpful too.
Thanks in advance,

Peter

Mass flow will be determined by the allowable pressure loss through the pipe. Since you are looking for charts you might contact Vilter or Frick for one of their engineering manuals. They offer some of the shortcut methods you are looking for.

Otherwise, you need to do some hand calculations or write a program....;)

I agree with Iceman for the ammonia info. For water a good resource manual is published under the name Cameron Hydralic data, at least it was years ago.

Yes US Iceman, Frick gave Enginnering and data tables:D
