Consider the following air pollutants: 1. NOX (oxides of nitrogen) 2. PAN (Peroxyacytyl nitrate) 3. CO2 (Carbon dioxide) 4. CO (Carbon monoxide) Which of the given air pollutants is/are present in an automobile exhaust gas?

Consider the following air pollutants: 1. NOX (oxides of nitrogen) 2. PAN (Peroxyacytyl nitrate) 3. CO2 (Carbon dioxide) 4. CO (Carbon monoxide) Which of the given air pollutants is/are present in an automobile exhaust gas? Correct Answer 1, 3 and 4

Explanation:

Emission from petrol engines contains a greater concentration of HC, CO2, and CO while the four-stroke diesel engines (buses and trucks) contain a greater concentration of NOx in addition to thick smoke and particulate matter.

AIR POLLUTANTS can be broadly classified into two general groups -

  1. A primary pollutant is an air pollutant emitted directly from a source. Eg. Particulates, COx, SOx, NOx, Bacteria, Fog, Soot, Dew, etc
  2. A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere. Eg. Ozone, PAN, PBN, PPN, Smog, CFC, and Acid Rain

A passage with three blanks,followed by five options, each containingone word, is given. Choose the word thatcan fill all the three blanks.
Emission ____________ are the legalrequirements governing air pollutantsreleased into the atmosphere. Emission___________ set quantitative limits onthe permissible amount of specific airpollutants that may be released fromspecific sources over specifictimeframes. They are generallydesigned to achieve air qualitystandards and to protect human life.Many emissions ____________ focus onregulating pollutants released byautomobiles (motor cars) and otherpowered vehicles. Others regulateemissions from industry, power plants,small equipment such as lawn mowersand diesel generators, and other sourcesof air pollution. While this have beenused to dictate limits for conventionalpollutants such as oxides of nitrogen andoxides of sulphur (NOx and SOx), thisregulatory technique may be used toregulate greenhouse gasses, particularlycarbon dioxide (CO2). In the US, this isgiven in pounds of carbon dioxide permegawatt-hour (lbs. CO2/MWhr), andkilograms CO2/MWhr elsewhere.
One of the main causes of air pollution in cities is emissions from vehicles like cars and trucks. Cars emit various pollutants which are bad for human health when inhaled, like 1) Nitrogen oxides (NOx) 2) Carbon monoxide (CO) 3) Carbon dioxide (CO2) 4) Benzene Which of the above pollutants are not tolerated by human beings even at very low levels?
In this question, a passage and a statement related to it have been given. Read carefully the verse and review the statement based on it. Delhi, which is one of India's capital an d one of the largest cities in the world, is undergoing severe crisis, due to its high level of urbanization, increasing population and high levels of pollution. Studies have proven that Are the biggest factors of pollution used for industrial and domestic use? And due to their use, people here emit large quantities of nitrogen oxides (NOx), ozone (O3), black carbon (BC) and microorganisms (PM). According to the 2015 Global Burden of Disease report, there were 1.09 million deaths due to PM 2.5 in India. Air pollution was included as one of the 10 biggest threats to health. According to the World Health Organization, 37 cities of India are among 100 worst polluted cities in the world, where PM10 was found to be the highest ever. For the production of ozone, together with sunlight and heat, nitrogen oxides (NOx) and organic compounds (VOCs) are needed simultaneously. Therefore, in the summer months, ozone is produced in large quantities in the cities. Statement: Air pollution is one of the top 10 factors affecting health in India.

In a newly developed innovative idea brought up by CSIR in India, gas turbine exhaust gas are being utilized to convert feedwater into steam. Certain data of the experiment are as follows: mass flow rate of exhaust gas = 40 kg/hr, enthalpy of exhaust gas at the time of their exit from gas turbine is 600 kJ/kg, steam turbine output as measured by brake dynamometer = 60 hp-sec, thermal efficiency of steam power plant is 0.25, efficiency of exhaust gas in converting feedwater into steam is taken as 50%. Find the enthalpy of exhaust gas remaining after they generate steam from feedwater?
In the carbonation of a soft drink, the total quantity of carbon dioxide required is the equivalent of 3 volumes of gas to one volume of water at 0⁰C and atmospheric pressure. Calculate (i) the mass fraction and (ii) the mole fraction of the CO2 in the drink, ignoring all components other than CO2 and water. Basis 1 m3 of water = 1000 kg Volume of carbon dioxide added = 3 m3 From the gas equation, pV = nRT 1 x 3 = n x 0.08206 x 273 n = 0.134 mole. Molecular weight of carbon dioxide = 44 And so weight of carbon dioxide added = 0.134 x 44 = 5.9 kg
