A circular cylinder of mass m, diameter D and length L is pulled vertically upwards within a cylinder of diameter of D + 2t by a force of magnitude P. If the mass moves with a constant velocity, U, and the cylinders are separated by a fluid with viscosity , what is the value of P? Is it: P= #DLUμ tmg P = #DLUμ t P= P = mg P= #DLUμ t DLUμ t - mg + mg

The flow rate of blood through a 1.75 ✕ 10−6 m radius capillary is 3.80 ✕ 10−9 cm3/s. (a)What is the speed of the blood flow (in cm/s)? (This small velocity allows time for diffusion of materials to and from the blood.) ________ cm/s (b)Assuming all the blood in the body passes through capillaries, how many of them must there be to carry a total flow of 96.0 cm3/s? (The large number obtained is an overestimate, but it is still reasonable.) ________ capillaries

You have a hose with a diameter of 9.0 cm from whose end the water leaves with a speed v. If a tube is connected to the end of the hose so that the water leaves with a speed of 3v, what must be the radius of the tube? The results of all problems must be expressed in SI units, unless the problem you indicate in other units.
In 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 Materials
