Growing a green roof has many environmental benefits include‚ absorbing rain water and preventing runoff‚ providing a habitat for wildlife‚ increasing agricultural space and decreasing urban air temperatures by soaking up the suns radiation to fight heat island effect (Alexander‚ 2004). There are many reasons why a green roof should be installed

physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions. The transfer of energy can occur in a variety of ways‚ among them conduction‚radiation‚ and convection. The SI unit of heat is the joule. Heat can be measured by calorimeter‚ or determined indirectly by calculations based on other quantities‚ relying for instance on the first law of thermodynamics. In calorimeter‚ the concepts of latent heat and of sensible heat are used. Latent heat produces changes of

HEAT GENERATED IN APPLIANCES Why do some appliances produce more heat than the others? Most appliances with high power rating are heating appliances.The heating appliances has a heating element like resistors. The resistorsconvert electrical energy into light and thermal energy . It depends on the resistance of material if how much heat can be produced from electricity. Those devices who produced heat‚ the Nichrome wire is an element who is responsible for heating . when we say nichrome

The FBI agent‚ Sarah Ashburn‚ only agreed to take on this case to get a promotion. The Boston cop‚ Mullins‚ was chosen to do this case because she knew the town better than anyone else did. Sarah Ashburn and Mullins did not like each other

Guano islands Along the Peruvian coast is a string of rocky islands and peninsulas that are home to guanay cormorants‚ boobies‚ and pelicans. The birds leave the islands every morning to feed on the fish‚ especially anchovies‚ that are plentiful in the Humboldt Current. They return in the afternoon. There is no vegetation on the islands‚ so they build their nests out of guano and feathers‚ adding a new layer every year. By the time Europeans first saw the islands‚ the guano was more than 100 feet

"The Island" SUMMARY The movie "The Island" is a movie about cloning‚ rights‚ and what it means to be human. It takes place in the future‚ presumably in 20 or 30 years. The two main characters are clones; one called Lincoln Six-Echo and the other called Jordan Two-Delta. They reside in a facility owned by a man named Dr. Merrick‚ together with many other clones. They believe that the outside world is contaminated and that the inhabitants of the facility are the sole survivors. That is the

Heat exchanger A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids‚ between a solid surface and a fluid‚ or between solid particulates and a fluid‚ at different temperatures and in thermal contact. In heat exchangers‚ there are usually no external heat and work interactions. Typical applications involve heating or cooling of a fluid stream of concern and evaporation or condensation of single- or multicomponent fluid streams. In a few heat exchangers
