Engineer who has been out of school too long to have any practical knowledge left needs help.
Plant has an 8" diameter header full of 395 psi saturated steam. Off this, they have a 2" line leading to a steam exhauster. The 2" line is approximately 125 feet long with 40 feet of rise from header to exhauster, (6) 90 degree elbows, and one Fisher 667ES diaphragm steam valve (cast iron).
I need to know the pressure and mass flow of steam at the exhauster when the steam valve is open. Plant cannot and will not put a pressure gauge at the exhauster. An answer plus a method that I could put into MathCAD for use the next time this comes up would be helpful. Thanks.
