Hydraulics – CIVL 2130 Conservation of Energy Aim The aim of this lab experiment is to observe the flow behaviour of water through a pipe of variable section. Firstly‚ we will investigate the interchange of pressure and kinetic energy at each diameter change. Secondly‚ we will study the application of this interchange to the flow metering devices. Lastly‚ energy losses due to friction and pressure effects are estimated. Experimental Apparatus [pic] Pre-lab Question Pressure varies

forces involved. Two of the main forces experienced are called potential energy and kinetic energy. Potential energy is the energy an object has depending on the position of it. For example the higher an object is the higher the potential energy is and the lower an object is the less potential energy it will have. Kinetic energy is also a main type of force that is involved with rollercoasters. Kinetic energy is the energy an object will have as it is in motion. There are many different types of

renewable energy? Well‚ because its renewable. Renewable energy will last forever and it cost close to nothing to get it. But it will always be their‚ unlike coal that once its gone‚ its gone. I think that the best process to get renewable energy is through geothermal plants. Some scientists think that the amount of geothermal energy stored in the earth will outlast our energy consumption and it may even outlast the sun. (Energy Informative) Geothermal is the most cost effective way to get energy‚ with

The Coming Energy Crisis? • • All warning signs that existed prior to the energy crises of 1973 and 1979 exist today. Various energy security measures indicate that the potential for an energy shortage is high. As submitted to Oil & Gas Journal for publication February 3‚ 2003 James L. Williams‚ President‚ WTRG Economics E-mail: wtrg@wtrg.com Phone: (479) 293-4081 I. Introduction Various measures of US energy security indicate that the US might be heading for an energy crisis.

McKenzie Smith Science 8-5 February 10‚ 2011 RSV Final Draft Energy Pathways This reading is about food chains‚ food webs‚ and food pyramids. The sun is the source of energy in a food chain. The energy from the sun can only be used by producers. The producers get eaten by consumers. A consumer is a herbivore‚ a carnivore‚ or an omnivore. Fungi and decay bacteria are decomposers. Decomposers break down and recycle dead things and make the soil better for producers. Food webs are the overlapping

2013 Energy Lost . . . Energy Saved . . . My family and many others have been tricked by the media. We have probably all – at one time or another – been succored into to buying an appliance or electrical device based off whether it’s the cheapest one. By doing this you have been fooled by society! Your purchase should not be based on price‚ but by how much energy the appliance consumes. The appliance might be cheaper‚ but it mostly likely uses a considerably larger amount of energy than the

atmosphere–ocean system and motivates the deeper examination to follow. The character of coupled atmosphere–ocean interactions is briefly introduced. Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude‚ latitude‚ and season. The global annual mean energy balance is then presented and briefly discussed. Finally‚ the origins‚ thermodynamic structure‚ and composition of the atmosphere and ocean are summarized.

Energy and the Environment “The Climate for Change” by Al Gore. As a whole I do not believe everything that Al Gore tells us. I think he is a hypocrite. He sits here and criticizes us for burning too many fossil fuels and our carbon footprints are too big! Well Mr. Al Gore‚ what about all the fossil fuels that you burn? Do you not have your own private jet that flies you around the world to talk about global warming? You‚ Mr. Al Gore‚ are just as bad if not worse than the rest of us. Al Gore

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming
