In a flash of insight, you remember how hydraulics work, and you set out to build a hydraulic jack. On the whale side, the piston area is to be 1.0 m 2. a. If you can push on the jack with a force of 120 lbs, what piston area must your side have to successfully lift the whale? Neglect whaletissue deformation, and remember that pressure is transmitted throughout a fluid and is only a function of depth, density, and gravitational acceleration. b. If the fluid in the hydraulic jack is incompressible, and you pushed your side of the jack down by 0.75 m, how much would you raise the whale? c. As gases build up in the whale, a cavity with a volume of 40 m 3 expands in the whale. If the pressure inside reaches an exciting 2x10 5 Pa at 310 K, how many moles of decayedwhalegas are inside? Are you prepared for this, Erik? inside joke. 18. Jupiter s icy moon Europa is thought to have an ocean as much as 100 km deep under its ice cap. Many scientists see this moon as having great potential to harbor life, and would like to visit the ocean floor to check for hydrothermal vents. You are tasked with designing a submersible which can descend to the dark depths of the ocean (with a crew member). Note that the gravitational acceleration on Europa is m/s 2, and the density of the water is likely similar to our own sea water, 1020 kg/m 3. The probe you design can be approximated as a sphere 2.0 m in diameter with a weight of 1460 kg including the crew. a. Issue number #1 is that your submersible needs additional ballast in order to be neutrally buoyant (so it can sink). Determine the mass you must add inside the sphere in order to be neutrally buoyant. b. What is the fluid pressure at the bottom of the ocean your submersible must contend with? c. What is the total force on the outside wall of your craft? d. The implosion of spherical shells is well modeled by the following equation*: P CR = 0.37 Et2 R 2, where E is Young s Modulus for a given material, R is the radius of the shell, and t is the thickness of the shell. If the submersible is built with carbon fiber (E = 90 GPa), how thick does it need to be? Page 4
5 19. Consider the crosssection of a volcano shown below. The magma chamber is located 1.8 km below the surface, and the magma has a density of kg m3. The absolute pressure in the magma chamber is 70 MPa. a. If the magma chamber is large, we may assume that the fluid velocity in it is negligible (i.e., zero). Determine the velocity of the magma once it reaches the surface where the pressure is atmospheric pressure. Hint: Consider the Bernoulli Equation here. b. Next, using kinematics (or the Bernoulli equation again), determine the maximum height of the magma jet (labeled h in the figure). c. Finally, if the magma is blasted out of a circular vent 75 m in diameter, what is the rate of lava erupted (in kg/s)? Dimensional analysis might be handy. 20. Here s something amazing about the human body. When your heart beats, blood moves through your 1.2 cm diameter aorta at approximately 40 cm/s. Assume the blood has a density of 1000 kg/m 3. Your blood vessels keep branching until they reach the size of capillaries 10 m in radius. These are so narrow that blood cells must pass through them singlefile at 0.03 cm/s. a. So, consider conservation of mass, assume all of the blood leaving your aorta passes through capillaries, and determine how many of these capillaries are fed by the blood from your aorta. The absolute pressure in your blood vessels varies, but it is generally about 15 mmhg (2000 Pa) in your jugular vein during a heartbeat. Furthermore, it passes through the jugular vein at 0.35 m/s. Now, this might sound morbid, but it is important for crime scene investigators: if your jugular vein is cut 1.6 m above the ground. b. What would be the velocity of the blood leaving the jugular? Hint: Use good ole Bernoulli. c. Using kinematics, determine how far from the body this jet could spray assuming it leaves your vein horizontally. Page 5

Well, you have shifted the colony to a polar region in order to start producing hydrogen fuel for a return mission, and now the gas in the engine starts at an initial volume, pressure, and temperature of 0.1 m 3, 0.8 kpa, and 60 K, respectively. a. How many moles of Martian air are present in the engine? Next, the fixed amount of gas is heated more than before to 700 K, causing it to expand to 0.2 m 3. b. What is the new pressure of the gas? During the next part of the cycle, the pressure returns to its initial state while the gas is compressed to a volume of 0.15 m 3. c. What is the temperature of the gas at this point? Finally, the gas returns to its initial volume, temperature, and pressure. d. Sketch the PV diagram and calculate the work done by the engine in one complete cycle. * Page 6
