What variations in the formulas must be introduced to actually calculate mass rates at pressures/temperatures different to standards? Upvote 0 Downvote Mar 6, 2002 #6 TD2K Chemical Jan 11, 2002 2,629 I'm not sure what you are asking. Flowrates in SCFH (or any other similar units) ...
Note that the friction coefficient will be of the order of 0.15 to 0.20 because the contact pressures on the threads are quite high. Hasalloy may have a different friction coefficient. Check whether galling is a problem. If it is then apply an anti-galling compound, or simply grease the ...
