- 1. The U-tube in the figure contains two liquids in static equilibrium: Water of density pw = 998 kg/m³ is in the right arm, and oil of unknown density px is in the left. Measurement gives l = 135 mm and d the density of oil. = 12.3 mm. What is Oil Water- InterfaceThe water flowing through a 2.1 cm (inside diameter) pipe flows out through three 1.2 cm pipes. (a) If the flow rates in the three smaller pipes are 27, 15, and 12 L/min, what is the flow rate in the 2.1 cm pipe? (b) What is the ratio of the speed of water in the 2.1 cm pipe to that in the pipe carrying 27 L/min? (a) Number i Units (b) Number i Units1. Fluid Flow: Water runs into a fountain, filling all pipes, at a steady rate of 0.750 cubic meters per second. How fast will it shoot out of a hole 4.50 cm in diameter?
- The flow rate of blood through a 2.00×10-6 -m -radius capillary is 3.80×109 cm3/s . (a) What is the speed of the blood flow? (This small speed allows time for diffusion of materials to and from the blood.) (b) Assuming all the blood in the body passes through capillaries, how many of them must there be to carry a total flow of 90.0 cm3/s ? (The large number obtained is an overestimate, but it is still reasonable.)Hot water with a density of 980 kg/m3 flows through a 51.2 mm diameter round pipe at 1.25 m/s. What is the mass flow rate (in kg/s) of the water How many significant figures should be used in the final answer?Suppose blood is pumped from the heart at a rate of 5.1 L/min into the aorta of radius 1.3 cm a. Determine the speed of blood through the aorta, in centimeters per second.

- Blood is flowing through an artery of radius 2.3 mm at a speed of 35 cm/s. a. Determine the flow rate through the artery, in cubic centimeters per second. b. Determine the volume, in cubic centimeters, that passes through the artery in a period of 30.0 s.6The aorta is the principal blood vessel through which blood leaves the heart in order to circulate around the body. (a) Calculate the average speed of the blood in the aorta if the flow rate is 5.0 L/min. The aorta has a radius of 10 mm. (b) Blood also flows through smaller blood vessels known as capillaries. When the rate of blood flow in the aorta is 5.0 L/min, the speed of blood in the capillaries is about 0.33 mm/s. Given that the average diameter of a capillary is 8.0 µm , calculate the number of capillaries in the blood circulatory system.
