1.25.(23) A disperse system is given with the mass of the dispersed phase m, the density of the dispersed phase m, with particles of the dispersed phase of a certain shape and size: r is the radius of the ball, l is the length of the cube edge (task options are given in Table 1.2).
1. Calculate the dispersion of the system D and the specific surface area Ssp.
2. Calculate the parameters of the particle of the dispersed phase: volume V0, surface S0, mass m0.
3. Calculate the total surface of all particles S and the number of particles N in the dispersed system.
Option 23
The dispersed phase is AgCl, the dispersion medium is water, the shape of the particle is a ball, r (l), m - 3 * 10-6, p * 10-3, kg / m3 - 5.6, m, kg -2.
