1. Manager 2015 Paper 2 (Civil) · Q84 · Environmental Engineering · Solid Waste & Pollution

   The dispersion of pollutants in atmosphere is maximum when

   1. Environmental lapse rate is greater than adiabatic lapse rate
   2. Environmental lapse rate is less than adiabatic lapse rate
   3. Environmental lapse rate is equal to adiabatic lapse rate
   4. Maximum mixing depth is equal to zero
   Show answer

   Answer: (1) Environmental lapse rate is greater than adiabatic lapse rate

   When the environmental lapse rate exceeds the adiabatic lapse rate (super-adiabatic condition), the atmosphere is unstable, rising air keeps rising and vertical mixing is strongest; a lower environmental lapse rate gives stable air and poor dispersion.
