The law of conservation of energy states that the total energy of an isolated system is constant. Energy can be transformed from one form to another, but can neither be created nor destroyed. In which we investigate issues concerned with electric energy and electric equipment, and how careful design of electric installations can contribute significantly to reduction in pollution of the local and global environment. To this effect: a) Define pollution in the context of production of mobile phones; b) Report on the environmental impact of retired cellular phones; Interpret the transformation of energy from electric energy to sound energy; d) Question the transformation of chemical energy to electric energy in mobile phones; Value chemical energy; a source of energy of mobile phones.

What will be the amount of air supplied, if 4 kg of oxygen is required per kg of volatile solid destroyed, which is 30% of total volatile sited present? The air supplied has density of 1.25 kg/m³, oxygen content in air is 25% and total volatile solid present is 1200 kg/day. Assume efficiency of transferring 02 is 20%.
How do I convert 10649 KWh into (KWh/(m2-yr)?
Describe geothermal energy and how we harness it, and evaluate its advantages and disadvantages
A home is heated with propane with a 100,000 BTU furnace size and 95% efficiency. The monthly heating degree days is 5000. Using the energy estimation discussed in this chapter, estimate the monthly and annual gas consumption to heat the building if the home is to be kept 68°F.
Calculate the emissions of NOx from all the vehicles in Orange County, Florida, in 2008. The fleet-average NOx emission factor for 2008 was 1.645 g/mi and the total vehicle miles traveled (VMT) in that year were 13.53 billion miles,
Propane is flowing in a 4-inch schedule 40 steel pipe at the minimum rate for which the flow is turbulent. Calculate the energy loss per 50 feet of pipe. Use Moody's diagram.
16 Which of the following statement is true about eco-properties of material production? * O co, footprint is the amount of CO, released into the atmosphere per unit mass of produced material. None of them. All of them. Embodied energy is the energy to produce unit mass of usable material. It is not feasible to estimate embodied energy via the thermodynamics of the processes involved in material production because the thermodynamic efficiencies of processes are quite low. The embodied energy can be found by monitoring the total energy input to the production plant and dividing this total by the quantity of usable material shipped out of the plant over a fixed period of time.
Find the estimated annual emissions of NOx, VOCs, SO2 and PM for the United States for two historic years (say 2000 and 2019) with information about major categories (e.g., mobile, non-mobile, EGU, area, etc.). Likewise, find the CO, NO2, ozone and PM2.5 concentrations for similar years in your city of choice (look at annual PM2.5 and 4th highest 8-hr ozone, you can choose which CO and NO2 metric to consider). Discuss how the emissions have changed by category and link that to how the concentrations have changed.
In 2016, about 30 million tons of combustible municipal solid waste (MSW) was generated in the United States. One ton of MSW burned in waste-to-energy plants in the United States, generated about 474 kWh of electricity. If the average annual electricity consumption for a U.S. residential utility customer was 10,399 kilowatthours (kWh). How many households could use this amount of electricity?
In 1908, what fraction of U.S. NOx emissions was contributed by highway transportation? By electric utilities? What were these fractions m 2008?
