Interesting, very interesting. Actually i thought that once a
pipe is choked, the intensity of choke will remain constant.
Meaning, once choked, there won't be such a thing call "more
choked" or "less chocked".
coz the back pressure ratio will not change one a pipe is
chocked.
2ndly, we are trying to get the gas out as quickly as possible
right, so is it that we prefer the pipe to deliver more gas, just
make sure that it doesn't choke?
thanks for reply =)
if cannot understand, e-mail me then, think this is a great
topic
