- 1 1.31 If the U.S. fleet of vehicles suddenly became 15% more fuel effi- cient, how much annual emissions of CO2 would that prevent? Assume the following: 200 million vehicles in the U.S., each driv- ing (on average) 12,000 miles/year, with an average fuel economy of 18 mi/gal. Also assume each gallon of gasoline contains about 5 lb of carbon.Can I get a thorough step by step for the following question? Each month the speedy dry-cleaning company buys 1 barrel (0.160 m3) of dry-cleaning fluid. The amount of the fluid lost to the atmosphere is about 232 kg/month and the remaining remains as residue to be disposed of. The density of the dry-cleaning fluid is 1.5940 g/mL. Draw a mass-balance diagram and estimate the monthly mass emission percentage to the atmosphere.1. Based on the water filter activity, how would you design a water filter to clean the water you would be using at home? a. What pollutants would you need to filter out? b. What materials would you use to filter each kind of pollutant?
- A family consists of an adult male weighing 70 kg, an adult female weighing 50 kg, and a child weighing 15 kg. The air they breathe contains 1 µg/m3 of a listed carcinogenic chemical, and the waste they drink contains 1 µg/L of the same chemical. Assume the air intake for adult and child is 20 m3 /day and water intake for adult and child is 2 L/day. The body retains 80% of the air pollutant and 100% of the water pollutant. Estimate the total chemical dose per kg of body weight for each family member per day correctly.Each month the Speedy Dry Cleaning Company buys 1 barrel (0.160 m3) of dry cleaning fluid. Ninety percent of the fluid is lost to the atmosphere and 10 percent remains as residue to be disposed of. The density of the dry cleaning fluid is 1.5940 g/mL. Draw a mass balance diagram and estimate the monthly mass emission rate to the atmosphere in kg/moIn 1908, what fraction of U.S. NOx emissions was contributed by highway transportation? By electric utilities? What were these fractions m 2008?
- Question 10 Carbon monoxide emissions are the result of incomplete oxidation of O Carbon in the waste to CO2 O Hydrogen in the waste to CO2 O Nitrogen in the waste to CO, Fluorine in the waste to co21 A woman works in a factory for 15 years. The drinking water in the factory contains xylene and fluoride. Her only exposure to these chemicals in water is at work. Using Table 10,find the hazard index associated with this exposure?Xylene: 0.6 mg/LFluoride: 3.1 mg/L5. USEPA sets standards for arsenic emission from foundry so that the unit cancer risk is 0.015 (per ug/m3 of arsenic in the atmosphere over a lifetime period). Assuming the exposure to arsenic is 25 years, what should be the maximum concentration of arsenic in ambient air in a way that the real risk of getting cancer during these 25 years is 0.0001 (one chance in ten thousand)?
- Question 14 In general, which of the following is the best long-term method of preventing the emis- sions of primary air pollutants? use of scrubbers and electrostatic precipitators to remove pollutants from industrial emissions B. use of taller smokestacks to release pollutants from industrial emissions higher into the atmosphere use of fossil fuels to fuel single-occupancy vehicles to reduce pollution from vehicle emissions D. use of air pollution reduction plans that promote the relocation of industrial facto- ries to less-populated areasYou are the Water Sanitation Engineer for Waterbury. Levels of bacterial cells in the water supply must be undetectable, which, in terms of the equation, is <1 per mL of drinking water. A single addition of chlorine yields a log kill every 5 minutes. During a storm, levels in the incoming water reach 10,000/mL. You hold the incoming water in a treatment tank and give it a single hit with chlorine. If you add the chemical at 10 a.m., when will it be safe to open the valve and release that water for drinking? (Recall that 10 raised to the 0 power is 1.)List three examples of energy production and use practices that you think are unsustainable. Write a short paragraph for each explaining why they are unsustainable and how we might make each of them more sustainable.
