A 1-cm-diameter pipe leads to a showerhead with twenty 1-mm diameter exit holes. The velocity of the water in the pipe is v. What is the velocity of the water exiting the holes?
Two cylinders filled with a fluid are connected by a pipe so that fluid can pass between the cylinders, asshown in the figure. The cylinder on the right has 4 times the diameter of the cylinder on the left. Both cylindersare fitted with a movable piston a
A solid of relative density 1.3 will sink in water
Your teacher has asked you to determine the density of a liquid. You place a graduated cylinder on a balanceand measure the mass at different volumes. The data is displayed in the table.(A) Graph the data appropriately on the grid provided.(B) Why does th
A dam controls the water level of the lake behind it by opening a flow pipe to allow water to exit out the baseof the dam. The water level is 10 m above the pipe inlet. The pipe descends 20 m to the exit on the other side ofthe dam. The pipe diameters are
A string holds a 10-cm × 10-cm × 20-cm block of wood with a density of 600 kg/m3 underwater, as shown in thefigure.Imagine the string is cut. Calculate the initial acceleration of the block of wood.
Derive an equation to show that the buoyancy force is equal to the weight of water that is displaced by a floating object.
A soda bottle is filled partway with water. A tack is poked into the side to create a hole. The cap is removed fromthe bottle.This time, the bottle has two tack holes, one above the other, as shown in the figure below. The bottle is filledwith water, the
Three wooden blocks of different masses and sizes float in a container of water, as shown in the figure. Eachof the masses has a weight on top. Which of the following correctly ranks the buoyancy force on the woodenblocks?
Fluid enters the left side of the flow tube and exits the right side at a higher velocity, as predicted by the continuityequation.There are bubbles in the fluid as it flows from side 1 to side 2. Explain what happens to the size of the bubblesas they move
