Question
Transcribed Image Text:Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A, of 10.5 cm?, and
the right arm has a cross-sectional area A, of 5.30 cm². Two hundred grams of water are then poured into the right arm as
shown in Figure b.

Figure (a) shows a U-shaped tube filled with mercury. Both
arms of the U-shaped tube are vertical. The left arm with
cross-sectional area A, is wider than the right arm with
cross-sectional area Az. The height of the mercury is the
same in both arms. Figure (b) shows the same U-shaped
tube, but now most of the right arm is filled with water. The
height of the column of water in the right arm is much
greater than the height of the column of mercury in the left
arm. The height of the mercury in the left arm is greater
than the height of the mercury in the arms in Figure (a),
and the difference in height is labeled h.

- A pumping station uses a Venturi tube to measure the flow rate of gasoline. The density of the gasoline is p = 7.10 x 102 kg/m³, the inlet and outlet tubes, respectively, have a radius of 3.62 cm and 1.81 cm, and the difference in input and output pressure is P, - P2 = 1.20 kPa.

Determine the average speed of the blood in the aorta. If the diameter of the aorta is reduced to a diameter of 1.2am, but the volumetric flow is the same, what will the new speed of the blood be?arrow_forwardIn the process of loading a ship, a shipping container gets dropped into the water and sinks to the bottom of the harbor. Salvage experts plan to recover the container by attaching a spherical balloon to the container and inflating it with air pumped down from the surface. The dimensions of the container are 5.00 m long, 2.35 m wide, and 3.20 m high. As the crew pumps air into the balloon, its spherical shape increases and when the radius is 1.10 m, the shipping container just begins to rise toward the surface. Determine the mass of the container. You may ignore the weight of the balloon and the air in the balloon. The density of seawater is 1027 kg/m³. 434.54 X How does the weight of the container compare to the weight of the water displaced by the container and balloon when the container starts to rise? See if you can express the weight of the water displaced in terms of the density of the seawater and the dimensions of the container and balloon. kg Additional Materialsarrow_forward

- A lost shipping container is found resting on the ocean floor and completely submerged. The container is 6.4 m long, 2.4 m wide, and 2.9 m high. Salvage experts attach a spherical balloon to the top of the container and inflate it with air pumped down from the surface.. When the balloon's radius is 1.3 m, the shipping container just begins to rise towards the surface. What is the mass of the container? Ignore the mass of the balloon and the air within it.
