1. Introduction to the subject. Similarity of systems and plots. Heat sharing, flow, determination of heat transfer coefficient, dimensionless criteria. 2. Heat transfer. Heat transfer coefficient, heat transfer through a composite plate, composite cylindrical and spherical wall, thermal resistance, thermal insulation. 3. Heat exchangers. Types of exchangers, heat transfer coefficient of the exchanger, enthalpy balance of the exchanger, power of the exchanger, mean logarithmic temperature difference, cocurrent and countercurrent exchanger. 4. Heat sharing by radiation, principle of heat transfer. 5. Ways of solving problems of non-stationary heat sharing by conduction in solids. Technical meaning. 6. Heating and cooling of mixed reservoirs by heat transfer from the flowing fluid outside the reservoir. The method of calculating the temperature in the reservoir as a function of time from the heat balance. 7. Diffusion. Fick's first law. Definition of mass flow concentrations, velocities and densities. Local velocity averaged over mass, component velocity with respect to stationary coordinates, and with respect to local velocity. 8. Fick's second law, diffusion equation. Diffusion coefficient - an example of the method of determination. Convective diffusion - analogy with heat transfer. 9. Settlement. Forces acting on a particle. Settling speed. Archimedes' criterion, Lyashchenko's criterion. Network analysis. 10. Filtration. Suspension. Filtration machine. Cake filtration. The driving force of filtration. Filter cake washing. Drying. Preparing the filter for further filtration. Batch and continuous filtration. Filter partitions and types of filters. 11. Drying. Determination of moisture content of dried material. Binding of moisture in matter. Equilibrium moisture, sorption and desorption curve. 12. Drying curve and drying speed curve. Constant drying rate region, decreasing drying rate region. Critical point. Importance for the drying process. 13. Properties of air, enthalpy diagram of moist air, relative air humidity, relative mass fraction of humidity and other quantities determining the state of the air. 14. Material and energy balance of ideal convective dryers.
