Question

Can someone help me with quesion 9, 10 please?

Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is 1.65 times 105 Pa and the pipe radius is 2.90 cm. At the higher point located at y = 2.50 m, the pressure is 1.27 times 105 Pa and the pipe radius is 1.60 cm. Find the speed of flow in the lower section. m/s Find the speed of flow in the upper section, m/s Find the volume flow rate through the pipe. m3/s The approximate inside diameter of the aorta is 0.53 cm; that of a capillary is 12 mu m. The approximate average blood flow speed is 1.0 m/s in the aorta and 1.0 cm/s in the capillaries. If all the blood in the aorta eventually flows through the capillaries, estimate the number of capillaries in the circulatory system.
