Pressure Drop

[Petroleo]

Hello everybody,

I am wondering what would be a suitable maximum segment size for a pipeline pressure drop calculation with pipesim package? is a 3% of the pipeline length a good criteria?

Thanks,

hello,

since it is a computer software I dont think it will influence the computation time, you can try some segments and see how the pressure drop changes till there is no significant change.
if it is a non-compressible fluid the no of segments will not affect the total pressure drop.
if it is a compressible or two phase flow I'll try segments that give a DP per segment that is not greater than 10% of the inlet pressure to the segment, but here again since it is a computer program you can shorten the segments to get a more accurate result.

regards,
