1. Basic concepts of process engineering. Similarity of systems and plots. Heat sharing by conduction, flow, determination of the heat transfer coefficient, dimensionless criteria. 2. Combined sharing of heat by conduction and flow - heat transfer. 3. Heat exchangers. Types of exchangers, heat transfer coefficient of the exchanger, enthalpy balance of the exchanger. 4. Heat sharing by radiation. Radiation intensity, reflectance, absorptivity, transmittance, absorptivity-emissivity relationship, absolute black, absolute white, gray body, total emissivity, Stefan-Boltzmann law, Boltzmann constant. 5. Ways of solving problems of non-stationary heat sharing by conduction in solids. Fourier equation of heat conduction. 6. Heating and cooling of mixed reservoirs by heat transfer from the flowing fluid outside the reservoir. 7. Diffusion - 1. Fick's law. Definition of mass flow concentrations, velocities and densities. 8. Diffusion - 2. Fick's law, diffusion equation. Diffusivity - an example of the method of determination. 9. Convective diffusion - analogy with heat transfer. 10. Diffusion in metals, technical significance, systems, phases, mechanisms of diffusion in metals, theory of diffusion in metals. 11. Thermodynamics of real gases and vapors. Technical diagrams of the pair. 12. Properties of moist air, enthalpy diagram of moist air. 13. Drying. Properties of moist air, relative air humidity. Determination of moisture content of dried material. Drying curve and drying speed curve. Critical point. Importance for the drying process. 14.
