waterDefinition from Wiktionary, the free dictionary Jump to: navigation, search See also wáterFrom Wiktionary under the GNU Free Documentation License. Water is a chemical substance with the chemical formula H2O. Its molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions, but it often co-exists on Earth with its solid state, ice, and gaseous state, water vapor or steam. Water covers 70.9% of the Earth's surface, and is vital for all known forms of life. 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 on Earth 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 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. A recent report (November 2009) suggests that by 2030, in some developing regions of the world, water demand will exceed supply by 50%. 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% of freshwater is consumed by agriculture. From Wikipedia under the
GNU Free Documentation License What could be the source of water hammer? Q. It seems that plumbing in my house has a problem with water hammer. First, I thought it only occurs when toilet tanks are filling back with water, but I realized that it happens whenever water is used anywhere in home. It just that water hammer is not as bad when I use faucets. So I've been trying to figure out where or source of this water hammer. By listening to where the sound is coming from, and by touching the water pipe with my finger tips, I learned that sound is loudest where the main water pipe comes in through the concrete wall. I guess I can install a water hammer arrestor. But I am trying to understand why water hammer is occuring. Here is my guess. Please let me know what you think. There is a branch near this point where pipe… [cont.] Asked by oskeewow13 - Thu Jul 5 10:27:04 2007 - - 6 Answers - 1 Comments A. A Plummer once told me that the water hammer was caused by air in the water lines. To cure this he shut off the water at the main and drained all the line by opening all the faucets. After water quit running he turned the water back on leaving the all the faucets open after about a half hour he started turning the faucets off one at a time. When he was finished there was no more hammering sounds. When I say all the facuets I mean all outside and inside. Answered by mic1 - Thu Jul 5 14:19:39 2007 How do I get water faucets to run after toilet water was shut off for several hours? Q. Our toilets upstairs overflowed. The water was shut off for about 3.5 hours. The water throughout the house now is extremely low. I have turned the water back on the toilet upstairs and succesfully flushed it several times. How do I get the water to run as it did before the water on the toilet was shut down? Asked by HAH - Tue Jun 3 23:46:39 2008 - - 1 Answers - 0 Comments A. Had that problem before ,you might have the same.Alot of silk will form in the pipes and will let lose if the preasure is off of the pipes for any time.On your faucets there is a screw cap(were the water comes out) turn that off you might have to use a bit of force if they have never been screwed off before.Once off inside the cap you will find a water saver and a screen most likely the water saver is stopped up.If so you will be able to run the water at that point tap it lightly and rinse it off that should fix you right up.The water saver is a pain when clogged and it does slow the water alot.If it will not clean out discard it and just put the screen back in that keeps the water from spraying wild in the sink .

Q. My house is not too too old, but not new. When I move it, i was nine, the owner son just graduate from university. The owner build the house. So that's about how old is the house. Everytime I take a shower, it's like a race, I have to do it as fast as possible before the hot water runs out. A handy man had come over, and he said and switch the temperature of the hot water hotter (he did it at the hot water production machine located at the laundry room), that's all he can do. But switching the hot water temperature hotter doesn't help make hot water last longer. I thought it was just me taking shower too long, but I ask my friend, and she said she took very long and hot water still did not run out. How to make hot water don't run out so… [cont.] Asked by asknanswer - Sun Mar 19 10:38:37 2006 - - 9 Answers - 1 Comments A. I assume you have an electric water heater. If so I suspect one of the elements is burned out or one of the thermostats is bad. Electric water heaters have two thermostats and two heating elements. If one of the elements burns out or one of the thermostats quits working you don't get enough hot water. But first connect a hose to the outlet at the bottom of the tank and run water out of it for 10 minutes. See if clearing the sediment helps. Sometimes sediment keeps the bottom element from working right. If it doesn't help then it is either a thermostat or heating element in which case you should call a service man and have it repaired.
