6. When a 0.96 meter long cylinder with cross-sectional area of 18 cm² is immersed in a tank of seawater (use p = 1.032 g/cc), 16 cm of the cylinder floats above the fluid surface. A) What is the density of the cylinder in g/cm³? B) What additional amount of force would be required to lift the cylinder so that only half of the cylinder is submerged? 7. Calculate the diameter of a spherical float (beach ball) that could suspend a fully submerged 0.25 m³ block of Aluminum, assuming that exactly HALF of the float would remain above water. Assume that the float is filled with air and has negligible weight. 8. Water flows with velocity 2.828 m/s through a pipe having cross-sectional with dimensions of 48 cm x 400 cm. If the downstream end of the pipe is partially crushed so that the area of the opening is now 12 cm x 180 cm, what would be the velocity of water flowing out of the pipe? 9. A 5.3 m diameter water tank is filled with water to a level 18 meters above a spigot located underneath the tank. The tank is open at the top. If the diameter of the opening in the spigot is 40 cm, what is the velocity of water flowing out of the spigot when it is opened up?
