Ocean Thermal Energy Conversion (OTEC) Essay

We are quite certain that in the upcoming years OTEC will become a much more publicized topic and greater research will come about to produce a fully sized commercial plant.This upper layer of warm water is very uniformed in temperature because wind and waves cause the water to circulate and mix.Most of the solar energy is absorbed in the top layer (35 to 100 m) of water.The colder water at these great depths is the result of melting ice in the polar regions.The colder water has a higher density than the warmer water which causes two important events.

Measurements: Accuracy and Precision

Calculate the mass of 10ml of water in the graduated cylinder using 1/5 the volume calculated in #5 above and the density of water of 1.00 g/mL.One of the reasons could be that I couldn’t successfully get all of the water from the 10ml cylinder to the 50ml cylinder.Being 100% sure that there is only 10ml of water in the cylinder when you start the experiment as well as using the proper utensils needed are a few ways to minimize errors.Calculate the mass of the water using the formula for density: Density = mass  volume .Convert the volumes of the water in the 10-mL and 50-mL graduated cylinders from mL to L, using the unit-factor method.

Water Cost Problem in United States: Expansion and Solution

When water becomes scarce due to the aforementioned causes, the public will be forced to brace themselves for tough water prices.Consequentially, water usage will decrease with the increase in water prices, hence being a serious challenge for America as a nation.This will ensure that water shortage is cut down, by some extent, since unequal distribution of water normally leads to this menace.The sudden water demand in these industries, has conversely led to water shortage, since there was no enough water reserves to counter such challenges.For example, regions which have large water demands should be allocated with, a relatively larger water resources, so that it would curb the whole problem.

Cause-Effect Essay: Deforestation

Additionally, the forest adds to local humidity through transpiration (the process by which plants release water through their leaves), and thus adds to local rainfall.Millions of acres burned as fires swept through Indonesia, Brazil, Colombia, Central America, Florida, and other places.In the water cycle, moisture is transpired and evaporated into the atmosphere, forming rain clouds before being precipitated as rain back onto the forest.The forest acts as a sort of sponge, soaking up rainfall brought by tropical storms while anchoring soils and releasing water at regular intervals.For example, 50-80 percent of the moisture in the central and western Amazon remains in the ecosystem water cycle.

Design Of A Sulfuric Acid Production Plant Engineering Essay

SO3 reacts with the water contained in the absorber acid to yield H2SO4.consist of adding water soluble compounds to gels or porous substrates and firing .Concentration of the chamber acid (62% to 68% H2SO4) is achieved by the hot gases entering the tower which evaporate water from the acid.The overall reaction can be described by the following equation, where sulfur trioxide reacts with the free water to produce sulfuric acid: .At higher concentrations the increased vapor pressure is caused by SO3 and at lower concentrations the water vapor pressure increases sharply and the resultant acid mist is not readily re-absorbed and escapes to the atmosphere.

Wind Power Versus Hydroelectric Power: Which is Better for the Environment?

Many hydroelectric power plants depend on the same similar basic rule as a historical water wheel.The method, conversion of flowing water to electricity, is known as very environmental process because no waste is created during energy generation.During the Industrial Revolution, hydro mechanical technology was developed based on simple water wheels from ancient times.Although both wind power and hydroelectric power have some disadvantages, I believe wind power is more useful than hydroelectric power because wind power will not produce any pollutants while hydroelectric power produces few minimal pollution.There could be changes in stream water quality and reservoir in some cases as well.

Biomass Energy and Biofuels

The fermentation must be followed by distillation to remove excess water in the mixture to reach the desired concentration (Banschbach & Letovsky, 2010).Another way to convert biomass is through biochemical conversion, the process by which biomass is broken down into gas, waste, and water by using enzymes and other microorganisms (Küçük & Demirbaş, 1997).Bioresource Technology, 101, 1570–1580.The biochemical processes refer mainly to aerobic fermentation that produces compost, carbon dioxide and water, anaerobic fermentation that produces fertilizer, and gas and alcoholic fermentation that produces ethanol (Küçük & Demirbaş, 1997).doi:10.1016/j.biortech.2009.11.046 Somma, D., Lobkowicz, H., & Deason J.
