Until you develop some awareness that providing meaningful help with a technical question requires some technical information the only answer you will likely get is: Good Luck.
ok
you are right
the idea is to install a new manifold to collect about 12000 bopd, and we have existing 8 in flowline, i am not sure wether 8 in is engouph ot not, i did made some calculations using pipedata software but the results was to use 6",which is litlle bit small.
what i want is very simple or concise procedure to determin the economic diameter
best rgards
it is a new manifold to be installed, we have existing 8" pipe we might use it, it depends on calculation.
the flow rate is about 12000 BOPD, i did some calculation with pipe data software but it seems not correct
all i need is a concise and understood method and formulas to determine the diameter necessary to transport this quantity of oil.
by the way such calculation should be done a process engineer, am i right.

Faridg, you need to look at the length of line and the flow and pressure drop you can tolerate. You then check a couple of line sizes. Since the pressure drop varies as the ratio of the IDs raised to the 5th power, you really only find you have a couple of choices.
For your question, will a 6" line pass 12000 BPD with a dP of 2 bar (the lower of the range you gave) over its given length? 12000 BPD is 350 gpm. In a 6" line this is less than 4 ft/sec.
