Gas Stagnation Conditions
Gas Stagnation Conditions
(OP)
Greetings,
I am attempting to model a steam distribution system - lots of pipe, elbows, valves, etc. The system essentially boils down to a 10 in main steam supply header feeding (28) 2 inch distribution lines each terminating with a perforated pipe sparger.
Ideally, one would assume the T & P conditions in the 10 inch pipe to be stagnant and allow the compressible gas flow solution for the 2 inch lines to develop based on inlet conditions. As the conditions in the 10 inch pipe are not really stagnant, I am unsure how to evaluate if the zero flow assumption is reasonably valid for my system.
Will a comparison of the static pressure head and velocity head of the flowing steam in the 10 inch line be an appropriate tool for the analysis?
Any help/insight will be greatly appreciated.

If it does, you'll need to do some trial and error work. If it doesn't, you are finished.
