PROBLEM 1
2. At the station for chlorination of drinking water located in the suburb of Dubovo, an unbound tank containing Gt of chlorine (ρ = 1.56 t / m3) collapsed. A cloud of contaminated air spreads in the direction of the city, on the outskirts of which, R km from the station, there is a store. The terrain is open, the wind speed in the surface layer is V m / s; convection. At the time of the accident, there were N people in the store, and the provision of them with CO gas masks was X.
Determine the size and area of the chemical contamination zone, the time the contaminated air approaches the city, the time of the damaging effect of chlorine, as well as the possible loss of people who find themselves in the store.
OBJECTIVE 2
12. To make an assessment of the air pollution of a settlement by emissions from a coal-fired thermal power plant based on data on the average annual concentrations of harmful substances.
