Comprehensive study of BS 6


BS 6 Norms
 Learning out come:
1)Introducing Bharat stage
2)Technology related knowledge
3)Environment impact
4)administration point of view

1)Bharat Stage:
>Vehcular Emmission Standard----Made by GOI to check air pollution @PPM.
>Who decides standard= Environment Ministry
>Who implements= CPCB (Central Pollution Control Bord)
>Globally(out side India) = European Emmission Standard.
>Current standard= BS6 ......yet to be implemented(2020 most probably)

>Comparing  BS4  and BS6



BS4
BS6
PM                (Particulate Matter)
50 PPM
10 PPM
Sulphur        (See environment section for impact @ 3)

80 % ↓
Nitrogne      (See environment section for impact @ 3)

70 % ↓






2)Technology related knowledge
>
To accomodate PM  (Particulate matter):
    >> Fuel refinary Upgradation
    >>Change in  Engine design
   
>> 2 Wheeler issue:
                  >>>Presently 2 wheeler uses = Carborate system in engine.
                             >>>>Carborate System= fuel+ air is mixed in required ratio then enters engine.
                  >>>Carborate system need to be replaced with= Fuel injection system.
                              >>>>This takes lots of time......@existing 2 wheeler poses challenge.

>To accomodate Gas norms:
    >>better Catalyst is required....usually in exaust pipe.

>To accomodate tracking system:
    >>On Board Diagnostic= a equipment fitted in vehcle....suo motu examines any deviation.

3)Environmental Impact:
>33.33 % of air pollution (1/3rd ) = Vehcular
>7 of the worlds top 10 polluted city is in India.


>SMOG (Smoke+ Fog)formation(Sulphur Vs Nitrogen) :
  >>Types =
1)Photochemical Smog       2)Industrial Smog
1)Photochemical Smog:
 
>Yellowish/ Brownish Color
 
>Source= Vehcular  fuel
 
>Whether condition = Dry + Sunny

  >Explain:
     >> NOx
=  from exaust of Vechle forms= NO2
     >>NO2 + UV rays = NO + O
     >> O +O2 = Ozone
= Ozone in bottom strata causes Resperetory disease + Plant disease etc.
   
     >>RC (Hydro carbon) + O = RCO (Aldehyde/Ketone) + O2
     >>RCO + O2 = RCO3 (Peroxide)
     >>Peroxide further boosts Ozone formation.

     >>Note= NO2 gives yellowish/brownish colour to Smog


2)Industrial Smog:
>Grey
color
>Source = Coal burning in industries.
>Wheather= Damp + Cool temp
>AKA “London Smog” = first found there
.

>Explain:
  >>Coal contains = Sulphur----After burning = Sulphor diaoxide.
  >>SO2 + H2O (Moisture= therefore damp climate)= Sulphuric Acid.
  >>Impact= irritation in eye + skin issues etc.

>Delhi Smog @ winter= combination of Industrial Smog + Photochemical Smog + stubble burning
>So, smoke from (Vechle +Industry + stubble burn) + (Fog) =Smog

>Health Impact = Lungs disease +Respiratory issues


4)administration point of view:
>Non Family Hardship Posting:
       --If pollution of Delhi does not improves---- delhi can be declared Non Family Hardship Posting.
          >Non Family Hardship Posting=
Diplomat posted there will need extra compensation...or will leave delhi.
>Sales are new limit for change:       
      --
earlier to adopt any new norms= Production unit was norms.....as a result when entire lots produce was sold then new norms on new production.
          >But
now,Sales are new unit= Even if Inventry has old goods you need to stop selling that if permissible sales quota is over.-------Potential of Corruption ....Current slowdown in Auto sector.

>Old Vechle= ensuring no old vehcle on road



Other impacts:
--
Cost of Vechle ↑ ......impact demand @india being cost sensitive market
--Air quality index monitors following gases:
  >PM = PM 2.5  and  PM10
  >CO
  >SOx
  >NOx
  >Ozone

evaporation

what causes water to evaporate every fluid (pure) has a definite vapor pressure at a fixed temperature , now if any how the partial presuure of the fluiid is less then the the vapor pressure of the fluid then the fluid starts evaporating to attain the partial pressure equal to the  vapor pressure of the fluid, and then the equllibrium is reached and evaporation stops.                              basically at the top of the fluid there is a random motion of the fluid molecule due to the difference between the adhasive and cohesive forces, some molecule say 'n' goes into the vapur phase and some strikes back say m such that n>m then after the above explained condition is achived then the constraint m=n. conclusion whenever there is the fluid in liquid state is  present then in that system partial pressure is exactly to the va...

The design of the policies and schemes meant to help farmers will greatly benefit intended beneficiaries if the definition of ‘farmers’ is unambiguous and comprehensive. Analyse.

 Science and Tech Defence: Kavkaz 2020: It is the  Russian strategic command-post exercise. Why in News? India will take part in the Russian Kavkaz 2020 strategic command-post exercise next month. The invitees for the exercise also include China and Pakistan apart from other member-states of the Shanghai Cooperation Organisation (SCO).
