max. velocity

THANKS,
   what is the recomended velocity in line sizing? in piping hand book,steam velocity is about 50m/s.   but i have seen in some spec. this velocity is between 20 to 30 m/s.

  but what is yr recomended velocity same as liquid(3-4 m/s)?   thanks Received on Wed Oct 15 01:55:00 2003
