- Fundamental terms of process engineering. Similarity of systems and actions. Conduction, convection, coefficient of conduction, non - dimensional criteria. - Heat passage. Heat passage coefficient, heat passage over compound board, compound cylindrical and ball side, thermal resistance, heat isolation. - Exchangers. Kinds of exchangers, heat passage coefficient exchanger, enthalpy balance - sheet exchanger, achievement exchanger, middle logarithmic temperature difference, uniflow and backset exchanger. - Heat interchange radiation. Emissivity, reflectance, absorption capacity, permeability, relation absorption capacity and emissivities, absolutely bull's - eye, absolutely whites, grey body, aggregate emissivity, Stefan-Boltzmann´s law, Boltzmann´s constant. Manners of problem solution of non - stationary heat interchange lead in stiff materials. Fourier-Kirchhoff´s equation of conduction. Meaning. Pedigree non - stationary field of temperature for "infinite board" - Fourierovou separation uncertain for border condition 3. kind. - Border conditions for Fourier-Kirchhof´s equation. Temperature conductivity. Concrete describing of kinds border conditions, meaning. - Warming - up and cooling assorted chambers heat passage from running liquids outside chamber. Method of calculation temperature in chamber depending on time from heat balance - sheet. - Diffusion. 1. Fick´s law. Definition concentration, at speeds of and densities flow masses. Local rate average out after quantity matters, rate components regarding immobile coordinates and regarding local rate. 2. Fick´s law, multiple centromere quadratic. Diffusivity - instance way assesment. Convection diffusion - analogy with passage of heat. - Separative method based on diffusion - absorption, adsorption, extraction, distillation, rectification. - Principle of filtration, technical meaning of the process. Manners of generating of overpressure and materials filtration septa. Suspension, filter cake, filtrate. Specific balance - sheet filtration. Filtration velocity . Application of automatic control - practice examples. - Using quadratic filtration in case of constant filtration velocity and constant pressure. Van filtration cakes. Assesment of filtration constants. Specific resistance of filtration cakes. - Sedimentation. Technical meaning, various dispersive systems. Force applied on single settling element, balance of power, Archimed´s and Lyascenk´s criterion, calculation rate settling or average insulated spherical coordinates element. - Principle function different settlers. Gravitational settler continual and non-continual. Influence concentration elements on sedimentation rate. Calculation share formed elements by the help of vibrating screen analyses dry mud. - Cure. Characteristics damp air, relative humidity. Assesment dampness dehydrated material. Structure dampness in matter. Break - even dampness, sorptive and desorption curve. Baking curve and curve rate cure. Region constant speed cure, region decreasing rate cure. Breaking point. Bearing on baking suit. Material flow and energy budget ideal oasts. - Fermentation process, kinetic modells, application automatic control to fermentation.
