Define temperature lapse rate and stability. What are the modifications of Gravity settling chamber? Explain
[3 marks]04 in brief. If following atmospheric condition exists in atmosphere, Altitude (m) 0 100 200 300 400 500 600 700 Temperature (°C) 31 28 25 22 24 26 28 30
[ marks]07 If the maximum daytime surface temperature is 35°Cand at a height of 10m, the average wind speed was observed as 4.5 m/s. What would be the ventilation coefficient? (Assume the value of n=0.20 for prevailing stability class and surface roughness and average wind speed is same as wind speed at the halfway of MMD.)
