The branching of a blood vessel is shown. Blood at a pressure of 100mg Hg (13.3kPa) flows in the main vessel at 4L/min. Ignore gravity. (a) Estimate the blood pressure for BRANCH 1, assuming that blood vessels behave as rigid tubes that we have frictionless flow and that the vessel lies in the horizontal plane. The answer should be in the unit of kPa. (b) Estimate the blood pressure for BRANCH 2, assuming that blood vessels behave as rigid tubes that we have frictionless flow and that the vessel lies in the horizontal plane. The answer should be in the unit of kPa. (c) Estimate the blood pressure for BRANCH 3, assuming that blood vessels behave as rigid tubes that we have frictionless flow and that the vessel lies in the horizontal plane.
