Without accurate data would not like to add to further to my "evasion".
Have found trying to estimate dP in different ID nozzles beyond me.
Will leave the "evasion" posted - graphs quite pretty(and maybe informative

EDIT: The shape also effects the spreading rate and turbulance levels.

Would be most interested in any links to any of this work.All are intuitively attractive.
