Question

A dam on a river is built so that the wall facing the water is shaped like the region above the curve y = 0.3x² and below the line y 100. All distances are measured in meters. The water level is 25m
below the top of the dam. The gravitational acceleration is g = 9.8m/s² and the density of water is p= 1000kg/m³. Find the hydrostatic force exerted on the dam.

Two identical cylindrical vessels with their bases at the same level each contain a liquid of density 1.18 g/cm3. The area of each base is 4.22 cm2, but in one vessel the liquid height is 0.790 m and in the other it is 1.56 m. Find the work done by the gravitational force in equalizing the levels when the two vessels are connected. Number Units Use correct number of significant digits; the tolerance is +/-2%
The figure below shows a stream of water flowing through a hole at depth h = 13 cm in a tank holding water to height H = 63 cm. H (a) At what distance x does the stream strike the floor? cm (b) At what depth should a second hole be made to give the same value of x? cm (c) At what depth should a hole be made to maximize x? cm
A thin stream of water flows smoothly from a faucet and falls straight down. At one point, the water is flowing at a speed of v₁ = 1.79 m/s. At a lower point, the diameter of the stream has decreased by a factor of 0.895. What is the vertical distance h between these two points? h = cm
A thin stream of water flows smoothly from a faucet and falls straight down. At one point, the water is flowing at a speed of v1=1.63 m/s . At a lower point, the diameter of the stream has decreased by a factor of 0.769. What is the vertical distance h between these two points?
A lost shipping container is found resting on the ocean floor and completely submerged. The container is 5.9 m long, 2.8 m wide, and 2.3 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 1.7 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. Do not neglect the buoyant force exerted on the shipping container by the water. The density of seawater is 1025 kg/m3.
A large dam has a hole that is 54 meters from the top. If the water in the reservoir is descending at a rate of 0.21 m/s, how fast is the water exiting the hole? V = unit m/s
The pressure in Pa is equal to 18 mm Hg times 133 Pa /mm Hg = 2394 Pa. Then set 2394 = ρ g h . Solving for h we get 2394 Pa /(10 m/s2 1000 kg/m3 ) = 0.2394 m.If you were helping in a blood drive, where would you hang the bag of donated blood?

Two identical cylindrical vessels with their bases at the same level each contain a liquid of density 1.30 * 10^3 kg/m3. The area of each base is 4.00 cm2, but in one vessel the liquid height is 0.854 m and in the other it is 1.560 m. Find the work done by the gravitational force in equalizing the levels when the two vessels are connected.
The flow rate of blood through a 2.25 ✕ 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.) (b) Assuming all the blood in the body passes through capillaries, how many of them must there be to carry a total flow of 80.0 cm3/s? (The large number obtained is an overestimate, but it is still reasonable.)
Air is evacuated from a vacuum chamber and the flow rate is measured. A section of circular plumbing is removed and replaced with a piece having a radius that is half the size of the original. The flow rate is measured again. What is the ratio of the new flow rate to the old flow rate?
The average body density of a human is 1030 kg/m3, yet we typically float in seawater when we fill our lungs with air and sink when we exhale. Therefore, our effective density is similar to that of seawater, 1010 kg/m3. If the typical total volume (body density + lung capacity) of a human is 0.25 m3, what volume is due to body mass and what volume is due to lung capacity (you can assume the density of air is rair = 1.2 kg/m3)

To verify her suspicion that a rock specimen is hollow, a geologist weighs the specimen in air and in water. She finds that the specimen weighs twice as much in air as it does in water.
