Solve the all parts of given problem:
Problem: The viscosity and density of blood are similar to those of water. For this problem, use 1000 kg/m3 as the density of blood, and 1.0 × 103 N•s/m2 as the viscosity.
Part I: The pulmonary artery, which connects the heart to the lungs, has an inner radius of 2.6 mm and is 8.4 cm long. If the pressure drop between the heart and lungs is 400 Pa, what is the average speed of blood in the pulmonary artery?
Part II: The human aorta (the body's largest artery, connected to the heart) has a diameter of about 2.0 cm, and at certain times the speed of blood flowing through it is about 55 cm/s. Is this blood flow turbulent? Support your answer with a calculation.
