In this paper, two-phase power law model blood flow model has been extended in three phase for human renal subsystem in case of dengue disease. Here, we have seen it from the perspective of a decline in hematocrit and blood pressure. Hematocrit and platelets are more affected by this disease than any other blood parameter. we have calculated the power index using a numerical methods for renal artery and. Finally, we have discovered a linear relationship between the decline in blood pressure and hematocrit datewise. max MBPD is 2609 pascal and min MBPD is 2333.11 pascal. of blood is 101.91 cm/sec at the axis of renal artery and vanished in wall of artery.
