the buoyancy of the object and its volume.

An object sinks when it's weight exceeds the weight of the amount of water displaced by it's volume. The density of pure fresh water is 1kg/l. Assuming the the bottle must be completely full to contain 2l of water, a 2l bottle of water will weigh 2 kg and displace 2 kg. It will have neutral buoyancy. The bottle itself will displace more than it weighs, so the bottle will float.

Water potential is the tendency of water to move from one place to another. It is typically measured in units of atmospheric pressure: pascals or pounds force per square inch or bars or dynes per square centimeter. It is a measure of the ability of a solution to absorb water by osmosis.

Often a dam can be installed that includes a weir for the water to pass through.  A wier is a slot cut out from the dam and may be shaped as a Vee, or rectangle or rectangle with Vee shaped sides, etc.  There are formulas in design books that permit you to estimate the flow of water through a weir based on its cross-secional area and the depth of water in the weir.  There is often a discharge coeficient that corrects for imperfect flow caused for example by thickness of the weir.  Small weirs can also be calibrated by collecting flow and measuring the collection rate.

stick it in a tank of water then measure the water displaced.archemedes law

When a stem is cut, water surges out of the stem for some time.  This proves that there is force which acts on the water.

I agree with answer one... depends on the size of the container\nThe spherical shape has the minimum surface area for a given volume (in this case for a given number of molecules, since each molecule occupies the same amount of volume).\n\nThis is why a drop of water is spherical. If we distort the drop, it “wants” to come back to its spherical shape, and the force pulling it back is what we call surface tension creating a meniscus. \n\nThis tension acts in a similar way as the stretched rubber in a balloon: if we distort the balloon and then release it, it comes back to the spherical shape.

The point to note is that the mass of the water in the cylinder is continuously varying.\nMass of can = M (constant)\nMass of water = M*(x/H)   -- because it is proportional to the height of the water column.\nCentre of mass of can alone (from the bottom)  = H/2\nCentre of mass of water = x/2\na) Centre of mass of the system = (Mass of can * cm of can+Mass of water * cm of water) / (Mass of can+Mass of water) \n = {(M*H/2) + (M*x/H)*x/2} / (M+M*x/H)\n = 1/2 (H^2+x^2)/(H+x)\n \nb) The value of x for the minimum height of the cm can be found out by putting d(cm)/dx = 0\n This gives, x = H*(sqrt2 - 1). \n At this value of x, the cm turns out to be:\n cm = H*(sqrt2 - 1).

You make a container 16 cm by 3 cm (and 1 cm thick) and pour water inside. The weight of the water in gm is your answer.\n\nAnother method is to use Napier's Bones. Just sliding and matching the numbers.

They restrict the width of where the water can go. The narrower the area, the faster the flow.

D= M/V\n\nIts a formula used to calulated to density (thinkness) of an object by dividing the Mass of an object by its volume. In this case, you can use the water displacement method that displaces (water) from its orignal volume by adding an object (marble). Using a balancer, measure and record the weight of graduated cylinder(ml), before and after the addition of water. Subtract the weight of the cylinder with water from the cyliner's weight and you will get the mass. You have to pay attention to how much the water displacement after adding the marble. record the volumes before and after (if ness). This will solve for volume. Once this is accomplished, you would have no problem finding the density.

You need to be a bit more specific about which quantities you are trying to determine.  "Flow" is not a quantity to be calculated.

Assuming the drop of water is a sphere or close to one...\n\nvolume of a Sphere = (4/3) * pi * radius^3\n\nTo find the volume of a drop, measure out a small volume of water into a graduated cylinder.\nUse a dropper to take drops and deposit them into another container.  Count the number of drops needed to empty the measured water.\nvolume of drop = measured volume / number of drops

Depends on conductivity of water which in turn depends on factors such as -- impurities present in water, temperature of water.

Boats do NOT displace more water than they weigh - the amount of water displaced is EQUAL to the weight of the boat. Salt water is heavier per cubic meter than pure water or fresh water, so a smaller amount of salt water would be displaced for the same weight boat. If the density of the solution was extremely high, as in mercury, the boat would appear to sit on top of the liquid.

Let B equal the weight of the boat, say in pounds.  Then B pounds of water will be displaced.\n\nSince there are 62.43 pounds of water in a cubic foot, then a boat of weight B pounds will displace B/62.43 cubic feet of water.\n\nIn your case, with a boat weighing 750 pounds, the boat will displace 12.01 cubic feet of water.  To determine how deep the boat is in water you need to know the geometry of the boat.
