1. Fundamental terms of process engineering. Similarity of systems and actions. Conduction, convection, coefficient of conduction, non-dimensional criteria. 2. Heat passage. Heat passage coefficient, heat passage over compound board, compound cylindrical and ball side, thermal resistance, heat isolation. 3. Exchangers. Classification of exchangers, heat passage coefficient exchanger, enthalpy balance - sheet exchanger, achievement exchanger, middle logarithmic temperature difference, uniflow and backset exchanger. 4. Heat interchange radiation. Emissivity, reflectance, absorption capacity, permeability, relation between absorption capacity and emissivities, absolute bull's - eye, absolute whites, grey body, aggregate emissivity, Stefan-Boltzmann´s law, Boltzmann´s constant. Solutions of non-stationary heat interchange conduction in stiff materials. Fourier Kirchhoff´s equation of conduction. Non-stationary field of temperature for "infinite board" - Fourier's separation of variables for the third condition. 5. Peropheral conditions for Fourier-Kirchhoff´s equation. Temperature conductivity. Records of the particular conditions. 6. Heating and cooling of chambers by heat passage from running liquids outside the chamber. Calculations of the temperature in the chamber depending on time using the heat balance. 7. Diffusion, Fick´s first law. Definition of concentrations, speeds and densities of flow masses. Average local rate depending on the quantity, rate of the components related to immobile coordinates and to the local rate. 8. Fick´s second law, diffusion equation. Diffusivity. Convection diffusion - analogy to the heat passage. 9. Diffusion in metals. Mechanisms of diffusion in crystalline materials. Diffusion conditions in metals. 10. Thermodynamics of real gases, equation of state of a real gas, wet, saturated, superheated water vapor, 11. 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. 13. Drying. Bond of humidity in substances. Balance, sorption and desorption curve. Drying curve and its rate. Region of a constant desiccation speed, region of a decreasing desiccation speed. Critical point. 14. Material and energy flow and energy in desiccation cabinets.
