Explain dry and wet adiabatic lapse rate with proper equations. A chimney with a design stack height of 300m is emitting sulphur dioxide at a rate of 600g/s on a sunny day in June (strong incoming solar radiation with unstable air conditions) with moderate wind speed (wind speed is 5m/s ) the stack altitude. Estimate the concentration of sulphur dioxide (in gm3) downwind for the following situations: (1000,0,0,300);(1000,50,0, 300):502>(1000,50,20,300)[3+3+9=15]
