Recently Asked air pollution Questions

Expert help when you need it

Q1:Topic 1 - Cause and solution of Air pollution Question 1 Air pollution has been a concern for many decades and experts in the field have been working to understand the causes in order to reduce them, what are the main causes that we see today and to what extent has the problem been reduced within the context of the EU? Support your views with relevant examples. Question 2 Will electric cars provide a sustainable solution? Electric cars have several benefits over conventional engines, including a significant reduction of local air pollution, especially in cities, as they do not emit harmful pollutants such as hydrocarbons and carbon monoxide but what are the drawbacks and concerns?See Answer
Q2:Topic 2 - Air pollution and EU policy Question 3 The WHO state that air pollution at current levels still poses a considerable burden on health in Europe. Many different adverse effects have been linked to exposure to air pollution, including an increased risk of heart disease and a reduction in life expectancy of a year or more for people living in European cities. The evidence is sufficient to strongly recommend further policy action to reduce levels of air pollutants, including particulates, nitrogen dioxide and ozone. In your opinion, what action should the EU be considering? Question 4 Should the EU have more policies in place to tackle reducing air pollution? Could the EU learn from other countries or is it leading in the field? Compare the issues of Air pollution in the EU with another country.See Answer
Q3:For this unit, we will complete our study of how to engineer indoor air quality, and we will continue to learn even more air quality engineering calculation steps required for an air permit. As we include our study of air quality for human health considerations, it may surprise you to realize that even noise pollution is considered an ambient air quality pollutant. Suddenly, we find ourselves incorporating safety engineering considerations into our environmental engineering work.See Answer
Q4: Unit 8 Question Welcome to Unit 8. In our previous unit, we learned about how to perform statistical modeling for engineered air quality, as well as to finish our air quality permit engineering calculations and analyze those calculated outcomes against the permit limits of the given state's Department of Environmental Quality (DEQ) office. For this final unit, we will be learning to utilize pollution control technologies for engineered air quality control. This means that you can now consider the available air pollution control options, and mentally select which technologies would have been most appropriate for the work system that you just quantitatively analyzed for an air permit.

Q5:Question 1 An electrostatic precipitator has 3 ducts with plates 12 ft long and 10 ft high. The plates are 8 inches apart. Assuming a drift velocity (Le terminal velocity in an electrical field) of 0.4 ft/s, calculate the efficiency (in fractions, i.e., 0-1) if one duct is fed 40% of the gas and the other two 30% each. The total volume flow rate to be treated is 4000 acfm. Note: In each duct, both inner sides of the plates should be counted for the collection area.

Q18: Based on the information provided below, make sure to make the PPT of 6 slide in APA referencing style The Scenario: You have contracted with an industrial organization to engineer and write a state air Permit by Rule (PBR) evaluation for a vehicle painting operation facility. According to the local state laws and U.S. Environmental Protection Agency (EPA) laws, the facility must have an air permit before construction begins. Once the facility is completed, the construction air permit will then become the operational air permit for the facility. As a result, your client wants the air permit to automatically align the painting operation facility into operational compliance with state and federal air quality laws. Consequently, it is extremely important for you to evaluate the planned painting operation against the PBR requirements in order to meet the air permit criteria, using the state guidance document and considering the equipment and chemicals already planned for the facility operations. You have tabulated the following information from what you have gleaned from each of the materials' SDS documents and equipment technical data sheets as a plan (each "unit" represents a single vehicle): Interior Liner Coating Material 10 gallons coating/unit 2 gallons of solvent/unit Unit Lining Application Unit Lining Curing Interior Liner Cure Unit Lining Design Exhaust Fan Air Makeup Unit Apply interior liners to two (2) units/day Cure interior liners of two (2) units/day Heater fuel source is natural gas-fired drying oven Cross-draft air plenum 10,000 ft/min (CFM) 5760 ft/min (CFM) Filter Openings Coating WV 20.0 ft² each VOC content Coating VM Coating volume Water Content Per gal/coating Work five (5) hours/day and four (4) days/week Work five (5) hours/day and four (4) days/week Heater generates 2.1 million (MM) Btu/hr at maximum 2,500 hrs/year Unit interior is the spray area 1 exhaust fan 1 air makeup system Two (2) filter openings 2.8 lb/gal coating 1.0 gal 1.0 lb/gal Water Density Per gal/water Coating VW Water volume 8.34 lb/gal Calculation Exempt-solvent Content Per gal/coating 0.5 lb/gal Exempt-solvent Density Per gal/exempt solvent 6.64 lb/gal Coating Ves Exempt solvent volume Calculation Additionally, your state's department of environmental quality (DEQ) has provided you the following PBR limits: Potential to Emit (PTE) 100 tons VOC/year Face Velocity 100 ft/min Filter Velocity 250 ft/min VOC/5-hour period 6.0 lbs/hr Short-term Emissions 1.0 lbs/hr Long-term Emissions 1.0 tons/yr From your first visit with your client, these are your notes and process flow sketch reflecting the intended operational design: • • • The client has designed an interior coating spray painting system that allows the interior of each unit to be coated. The operations will involve a stripped-down unit being brought into the facility's shop. The shop is a steel building with a finished concrete floor and a paint booth for each unit. The unit will be placed in the spray booth. The booth will be opened at one end of the booth for makeup air. The exhaust air will flow through an exhaust chamber at the other end of the unit. For each unit, once the liner application operations are completed, the forced curing (drying) operations will immediately commence. Booth Exhaust ChamberSee Answer
