1.25.(18) Given a dispersed system with a dispersed phase mass m, a dispersed phase density m, with particles of the dispersed phase of a certain shape and size: r is the ball radius, 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 18
The dispersion phase is camphor, the dispersion medium is water, the shape of the particle is a ball, r (l), m - 1 * 10-6, p * 10-3, kg / m3 - 0.99, m, kg - 1.
