From Wiktionary under the GNU Free Documentation License. Water is the ubiquitous chemical substance, composed of hydrogen and oxygen, that is essential for the survival of many known forms of life. In typical usage, water refers only to its liquid form or state, but the substance also has a solid state, ice, and a gaseous state, water vapor or steam. Water covers 71% of the Earth's surface. On Earth, it is found mostly in oceans and other large water bodies, with 1.6% of water below ground in aquifers and 0.001% in the air as vapor, clouds (formed of solid and liquid water particles suspended in air), and precipitation. Oceans hold 97% of surface water, glaciers and polar ice caps 2.4%, and other land surface water such as rivers, lakes and ponds 0.6%. A very small amount of the Earth's water is contained within biological bodies and manufactured products. Water moves continually through a cycle of evaporation or transpiration (evapotranspiration), precipitation, and runoff, usually reaching the sea. Over land, evaporation and transpiration contribute to the precipitation over land. Clean, fresh drinking water is essential to human and other lifeforms. Access to safe drinking water has improved steadily and substantially over the last decades in almost every part of the world. There is a clear correlation between access to safe water and GDP per capita. However, some observers have estimated that by 2025 more than half of the world population will be facing water-based vulnerability. Water plays an important role in the world economy, as it functions as a solvent for a wide variety of chemical substances and facilitates industrial cooling and transportation. Approximately 70 percent of freshwater is consumed by agriculture. From Wikipedia under the
GNU Free Documentation License What rate is the water level decreasing when the water is 2m deep? Q. A water tank has the shape of an inverted circulur cone with base radius 3m and height 10m. (a) If water is leaking out of the tank at a rate of 1m^3/min, at what rate is the water level decreasing when the water is 2m deep? (b) If the empty tank is being filled with water at a rate of 1.5m^3/min find the rate at which the water level is rising when the water is 7m deep. Asked by Shaily - Sat Apr 5 14:10:06 2008 - - 2 Answers - 0 Comments A. Volume of cone = V = (1/3)(pi)(r^2h) where r = radius of cone h = height of cone By similar triangles, (3/10) = r/h hence, r = 0.6h Substituting r = 0.6h in the volume formula for the cone, V = (1/3)(pi)(0.6h)^2(h) V = (1/3)(pi)(0.36h^3) V = 0.12(pi)h^3 Differentiating, dV/dT = 0.12(pi)(3h^2)(dh/dT) Solving for (dh/dT), (dh/dT) = (dV/dT)/(0.12 * pi * 3h^2) and at h = 2, (dh/dT) = (-1)/(0.12 * 3.1416 * 3(2^2)) (dh/dT) = -1/4.5239 (dh/dT) = -0.221 m^3/min. b) When the tank is being filled, the same original function and its derivative are still the same. Substituting dV/dt = 1.5 m^3/min h = 7 m then (dh/dT) = 1.5/(.12 * 3.1416 * 3(7)^2) (dh/dT) = 1.5/55.418 (dh/dT) = 0.027 m^3/min. Answered by Pointy - Sat Apr 5 14:36:01 2008 How much water do you drink daily? What type of water do you drink? Q. I drink a gallon of water each day, and since I no longer have water delivery, I usually go to walmart and purchase their 50 cent gallon bottles of water. Anyway, I'm thinking of just using tap water, but attaching a filter to the faucet. What about all of you? Asked by Miji - Thu Jan 25 21:13:28 2007 - - 11 Answers - 0 Comments A. I drink 1 gallon of water a day, at least. when I am strapped for cash I turn on my Brita purifier attached to my faucet and fill a few gallon bottles. Or I buy Distilled water. Answered by amarie828 - Thu Jan 25 21:29:00 2007 How can people say tap water tastes as good as filtered water?
Q. I did an experiment. I put some tap water in the fridge, and some filtered water in the fridge (from one of those faucet filter thingys). I drank both on a hot day. The tap water tasted like chlorine pool water. The filtered water tasted good. Now that I have stopped drinking tap water, the chlorine taste just jumps out at me. Why is the chlorine taste not obvious to most people? Asked by newell - Sat Aug 29 06:13:43 2009 - - 2 Answers - 0 Comments A. idk at my house, all the water is filtered. we have our own well.
