Blood flows via a section of a horizontal artery which is partially blocked through a deposit all along the artery wall. As a hemoglobin molecule moves from the narrow region into the broader region, its speed changes from v2 = 0.800 m/s to v1 = 0.643 m/s. Find out the change in pressure, P1 - P2, which it experiences? The density of blood is around 1060 kg/m3.
