Product description
1.25.(6) 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 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 6
The dispersed phase is flour dust, the dispersion medium is air, the shape of the particle is a ball, r (l), m - 5 * 10-5, p * 10-3, kg / m3 - 0.82, m, kg - 8.
