(a) Calculate the mass flow rate (in grams per second} of blood [p = 1.0 gr'cma'] in an aorta with a crosssectional area of 2.0 cm2 if the flow speed is 46 cmfs. |:| 9,. (b) Assume that the aorta branches to form a large number of capillaries with a combined crosssectional area of 3.0 x 103 cm2. What is the flow speed in the capillaries? S cm A liquid (p = 1.65 g/cm") flows through a horizontal pipe of varying cross section as in the figure below. In the first section, the cross-sectional area is 10.0 cm", the flow speed is 281 cm/s, and the pressure is 1.20 x 10" Pa. In the second section, the cross-sectional area is 3.00 cm . (a) Calculate the smaller section's flow speed. (Enter your answer to at least two decimal places.) m/s (b) Calculate the smaller section's pressure. PaWater moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is 1.85 x 10 Pa and the pipe radius is 2.60 cm. At the higher point located at y = 2.50 m, the pressure is 1.28 x 10 Pa and the pipe radius is 1.30 cm. P2 A (a) Find the speed of flow in the lower section. m/s b) Find the speed of flow in the upper section. m/s (c) Find the volume flow rate through the pipe. m 3 / s
