Blood flows via a part of a horizontal artery which is partly blocked by a deposit all along the artery wall. As a hemoglobin molecule moves from the narrow area into the wider region, its speed changes from v2 = 0.800 m/s to v1 = 0.580 m/s. Determine the change in pressure, P1 - P2, which it undergoes? The density of blood is around 1060 kg/m3.
