The large blood vessel leading from the human heart, the aorta, has an inside diameter of 1.0 cm and a length of 40 cm. The flowing blood (SG = 1.06) has a viscosity of 3.5 CP and an average velocity of 60 cm/s. Find the pressure drop across the aorta, if it is (a) horizontal, (b) vertical with upward flow, and (c) vertical with downward flow.

Answer #1

For Blood flow Hagen Poiseuille equation is used to calculate pressure drop due to viscous lossesWhen the pipe is vertical, the pressure drop is not just because of viscous losses but also due to hydrostatic pressure.

The human circulatory system delivers oxygenated blood from the lungs throughout the human body to enable the transport to and from body cells of oxygen, carbon dioxide, nutrients, hormones and blood cells. A variety of sizes of arteries and veins are required to ful?l this need. (a) A typical heartbeat pumps 75 mL of blood over a time span of 0.36 seconds into the aorta. If under this pressure the aorta expands to a diameter of 4.2 mm, what is...

Oxygen-rich blood bound for the body tissues leaves the heart through the aorta, the major blood vessel emerging from the heart. It branches out to the arteries, which in turn branch into smaller vessels called arterioles (little arteries). These then branch into tiny, thin-walled capillaries. Blood travels slowly as the red blood cells squeeze through tiny capillaries. The radius of the aorta is approximately 9.8 mm and the speed of the blood there is 30 cm/s. A typical capillary has...

A small blood vessel near the skin surface has a radius of 10 μm, a length of 1 μm and the pressure drop along the blood vessel is 2.50 Pa. The viscosity of blood is 0.0027 Pa.s. i. What is the volume flow rate of blood through this blood vessel? What is the velocity of blood flow? [6 marks] ii. Vasodilation causes the radius of this blood vessel to increase to 12 μm, while leaving the pressure drop along the...

The heart is supplied with 5L/min of blood from the vena cava (assume one pipe with a diameter of 20cm). The aorta discharges the heart and has a diameter of 26cm. Determine the pressure drop across the heart if it delivers 4uW during the process into the system. Density of blood 1050 kg/m3

An aortic aneurysm is a cardiovascular abnormality where the primary artery supplying blood from the heart irregularly increases in size, usually in the abdomen region. Because of the aneurysm, the radius of the aorta of a patient has increased in size as compared to a healthy aorta. The speed of blood through the healthy portion of the aorta 0.34 m/s when the patient is lying flat. The pressure difference due to the increase in artery is 30 Pa Consider the...
