A coal plant is functioning on a smooth terrain with a stack height 80 m height and the anemometer at the height of 15 m from the ground level. The anemometer reading shows that the windspeed is 3 m/s on a day with slightly stable atmospheric conditions. What is the windspeed at 350 m elevation from the ground? Determine the mixing height and plume rise level from the data given in the following table. Calculate the ventilation coefficient if 75% of mixing height is used for mixing depth? 8 Marks 200 300 400 500 600 700 Altitude (m) Temp, Celsius DALR, Celsius Plume DALR, Celsius 0 50 80 33 31 30 29 27.7 37 36 35.5 27 26 25 33 32 31 30 29 28 26 24 23 34 33 26 32 800 900 27 22 31 30 28 27 28 21 26 1000 30 20 25
