146. Solving a chemistry problem

Product description

• Calculate and plot in the coordinates (1 /) () nf = τ the curve of the change in the total number of particles during the coagulation of the mineral oil mist for the following time intervals τ, c: 60, 120, 240, 480, 600. The average particle radius r = 2 ⋅10 -7 m; concentration C = 25⋅10 -3 kg / m 3; density ρ = 0,97⋅10 3 kg / m 3. The half coagulation time is θ = 240 s.
