Blood flows from the heart (specifically, the left ventricle) into the aorta to feed the rest of the body oxygen. As blood flow moves from the ascending aorta and downward to the abdominal aorta, some of the volume is directed through a branching network. As the blood reaches the pelvic region, there is a bifurcation, as shown in figure, into the left and right common iliac arteries. This bifurcation is symmetrical but the common iliac vessels are not the same diameter. Given that the kinematic viscosity of blood is 4 cSt (centistokes), the abdominal aorta’s diameter is 15 mm, the right common iliac artery’s diameter is 10 mm, and the left common iliac artery’s diameter is 8 mm, determine the mean flow rate through the right common iliac artery if the abdominal aorta’s mean velocity is 30 cm/s and the left common iliac artery’s mean velocity is 40 cm/s.

Question

Blood flows from the heart (specifically, the left ventricle) into the aorta to feed the rest of the body oxygen. As blood flow moves from the ascending aorta and downward to the abdominal aorta, some of the volume is directed through a branching network. As the blood reaches the pelvic region, there is a bifurcation, as shown in figure, into the left and right common iliac arteries. This bifurcation is symmetrical but the common iliac vessels are not the same diameter. Given that the kinematic viscosity of blood is 4 cSt (centistokes), the abdominal aorta’s diameter is 15 mm, the right common iliac artery’s diameter is 10 mm, and the left common iliac artery’s diameter is 8 mm, determine the mean flow rate through the right common iliac artery if the abdominal aorta’s mean velocity is 30 cm/s and the left common iliac artery’s mean velocity is 40 cm/s.
