In this paper, numerical study was conducted on perforated pipes with phasing angle 180áµ’ and 90áµ’ respectively. The calculation were carried out with ANSYS FLUENT 15.01 using k- (RNG) model. It concluded from results there is no change in acceleration and frictional wall pressure between 180áµ’ and 90áµ’ perforation phasing. Total pressure drop in 90áµ’ perforation phasing has the highest value compared with 180 phasing angles due to intensified influence of mixing pressure drop. The decreases in additional pressure drop in 90áµ’ phasing has the lower value in compared to additional pressure drop at 180áµ’ phasing this is due to intensified influence of mixing effects pressure drop.
