daily lives. For instance‚ wave power‚ which is a very similar to wind power. It requires the generator to stand and hold on in extreme weather conditions without being damaged (Boyle‚ 2007). Wind power is a renewable energy source. That is due the buoyancy force‚ which is an upward acting force‚ caused by fluid pressure that opposes an object’s weight (Peng‚ 2007). In 1105 A.D.‚ the first wind power device was for grain grinding. These devices were controlled manually and oriented by adjusting the

Do you ever wonder why a boat floats and a rock doesn’t? Well I do. A Boat floats because of buoyancy and it remains lighter than the amount of water it displaces. Buoyancy is an interesting topic. Buoyancy can happen in any fluid and air. The buoyant force applies not just to water but to any fluid...A fluid is a substance that is able to take the shape of a container in which it is placed.” The source of this information is http://blackbirdlibrary.pbworks.com/w/file/fetch/70171466/dFlaoting

= \rho *gh Liquids are essentially incompressible substances‚ and thus the variation of density with depth is negligible. This is also the case for gases when the elevation change is not very large. at great depths such as those encountered in oceans‚ the change in the density of a liquid can be significant because of the compression by the tremendous amount of liquid weight above. For fluids whose density changes significantly with elevation‚ a relation for the variation of pressure with elevation

advanced reactor designs. A heat source and a heat sink connected by piping are the essential part of natural circulation loop. Here the heat sink is placed at higher elevation to promote natural circulation. The flow takes place due to the buoyancy force caused by density gradient resulting from temperature gradient. The natural circulation flow rate depends on the loop resistance and the temperature difference between the hot leg and the cold leg‚ as determined by the power level and the heat sink capacity

and it ensures a stable environmental temperature as water does not quickly heat up or cool down. Water has a high boiling point as a large amount of heat is required to overcome the hydrogen bonding. The high density of water allows many organisms to readily float on water. The buoyancy in water helps the swimming of motile gametes and in the dispersal of fruits and seeds. Hydrogen bonds hold water molecules together‚ therefore giving water the properties of cohesion and adhesion – leaves pull
