2 Fluids Fluids A flotation device is in the shape of a right cylinder, with a height of 0.500 m and a face area of 4.00 m 2 on top and bottom, and its density is 0.400 times that of fresh water. It is initially held fully submerged in fresh water, with its top face at the water surface. Then it is allowed to ascend gradually until it begins to float. What’s the initial acceleration of the rising cylinder? Is it a constant acceleration during the ascent? What is the height of the cylinder outside the water when it is floating in equilibrium? The plastic tube in Fig. 14-32 has a cross-sectional area of 5.00 cm 2 . The tube is filled with water until the short arm (of length ) is full. Then the short arm is sealed and more water is gradually poured into the long arm. If the seal will pop off when the force on it exceeds 9.80 N, what total height of water in the long arm will put the seal on the verge of popping?
