Question
Blood flows through a section of a horizontal artery that is partially blocked by a deposit along the artery wall. As a hemoglobin molecule moves from the narrow region into the wider region, its speed changes from v2 = 0.800 m/s to v1 = 0.548 m/s. What is the change in pressure, P1 - P2, that it experiences? The density of blood is 1060 kg/m3.
Blood flows through a section of a horizontal artery that is partially blocked by a deposit along the artery wall. As a hemoglobin molecule moves from the narrow region into the wider region, its speed changes from v2 = 0.800 m/s to v1 = 0.548 m/s. What is the change in pressure, P1 - P2, that it experiences? The density of blood is 1060 kg/m3.Explanation / Answer
P1 + 1/2 rho v1^2 = P2 +1/2 rho v2^2
P1-P2 = 0.5*1060*0.8^2 - 0.5*1600*0.548^2=98.96 Pa
