We wtórnych obiegach układów klimatyzacyjnych zazwyczaj wykorzystywana Jest woda lodowa względnie wodne roztwory soli, alkoholi lub glikoli. Wszystkie te czynniki mają matą pojemność cieplną, co przy transporcie dużych strumieni energii daje duże średnice rurociągów i moce pompowania. Większe możliwości transportu energii mają zawiesiny lodowe dzięki magazynowaniu chłodu w fazie stałej (kryształkach...
The paper is to present the developed thermodynamic characteristics of a solid. The existent description of dependence of temperature on the proper entropy (thermal capacitance) was used as the beginning point of the considerations. A critical evaluation of the picture of that dependence was a consecutive link of the considerations. Furthermore, an adequate description of the discussed heat phenomenon,...
The paper turns the attention to the thermal problems of the solid cooling in air. The physical aspect of mathematic approach has been underlined. The analysis and critical evaluation of Newton's Law concerning the solid air-cooling have been performed. The cognitive path leading to the solution is presented with the result being the body temperature dependence on time of cooling down in the air....
The paper covers an adequate theory on vertical motion of the mass-elastic system. This system is an oscillator with the motion being a free harmonic motion. The first extended link of the consideration presents a critical analysis of the existent knowledge referred to this subject. Then the energetic states of the oscillator have been determined. Next the force characteristics of the free harmonic...
The work covers the adequate kinetics of the flexibly fixed working element of a rotating device. First the literature background of the problem has been presented, turning the attention on such systems where the phenomenon of centrifugal displacement of a body due to the rotating of the system occurs. Then the general characteristics of the complex motion of working element has been described. The...
This work has been performed to verify the existent knowledge on determination of the mass moment. For the experiment, a compound pendulum was used. The motivation to undertake these studies were experimental results indicating a big discrepancy in mass moments between the values coming from calculations using the definition formula and these obtained from the experiment. In relation to the axial...
In the paper, a new adequate theory of a simple mathematical pendulum is presented. This paper consists of two parts. In Part 1, the behaviour of pendulum in particular points, that is in central and terminal/extremum ones have been analyzed very carefully in detail. System of forces in these points was considered with a special attention turned towards the terminal points where the equilibrium of...
This work is a continuation of the problems of kinetics and dynamics of solid on the example of a tool fixed flexibly under cutting. Present work is concerned on the development of work and energy. A special attention has been paid to the work description by underlying a distinctness and lack of connection with the energy notion. Polarization of these two magnitudes has been revealed. An adequate...
The paper is concerned on a new adequate theory of a simple mathematical pendulum. Part 1 of the paper was devoted to the behaviour of pendulum in particular points, that is central and terminal/extremum ones. This Part 2 of the theory begins with the analysis of path length of the pendulum weight. Then the kinetics of the pendulum weight is analyzed by separating and the descriptions of differentiated...
This work investigates kinetics, dynamics and energy of solid on the example of a tool fixed flexibly under the process of cutting. The original approach to the tool kinetics was considered by the Authors earlier. This work consists with three parts referred to the kinetics, dynamics, and energy of solid. Present work is concerned on the development of kinetics problems of a solid represented by a...
The paper presents a new adequate look on the character of motion of any material body, such as moving vehicle. It has been proved, that motion of material bodies has a quantum character. Due to this their consecutive energetic states are obtained by a jump. The phenomenon of quantum in the reference to vehicle kinetics has been derived by indicating its place on the background of characteristics...

The paper aims at the kinetics of a body under free fall, especially free body motion, the motion occurring in the Earth environs space, that is in the range of the gravity action. A new adequate theory of such a motion, opening new not known kinetic magnitudes, has been elaborated. This theory has its source, which is the dependence of the way length on time. That is the way characteristics created...
The paper discusses the groundless use of mathematics. This question has been explained mainly based on example of the so called d`Alembert’s rule which unfortunately still functions in science none the less it has been based on a fiction, contrary to the truth cognition as the fundamental purpose of science. That pejorative feature of the mentioned paradigm is marked very clearly in the paper to...
The work contains some of the elements of adequate quantum theory of impact phenomenon. These elements form the prelude to verification of the existent non-adequate theory of the impact phenomenon. At first a correct definition of impact has been formulated. For comparison, the interpretation of the elastic impact according to the existent knowledge is given. Then, taking advantage of the new correctly...
This work is a continuation of the problems of kinetics, dynamics, and energy of solid on the example of a tool fixed flexibly under cutting. The work consists with three parts. Part 1 covered the kinetics of the system. Present work is devoted to the dynamics of a tool in the machining space-time. Dynamic characteristics of the whole machining system are considered by determining forces being the...
In the framework of this paper a deep critics of existent theory of the simple mathematical pendulum is presented. This work consists of two parts. In the first part of the paper, a thesis is stated to derive a mystification character of the theory. The up-to-date, excerpted from the literature, descriptions of the oscillation motion of the mathematical pendulum, are delivered. This part of the paper...
In the second part of the paper, the thesis is proved to state that the existent theory describes simply a shadow of the rotating apparent mathematical pendulum. Hence, it appears, even that existent description is not sufficiently adequate. Finally, all defects of the theory, which resulted in so inadequate description of the oscillation motion of the simple mathematical pendulum, have been revealed...
The paper contains a proper approach to the Hooke's law as well as its developed version. A system approach was applied covering all the process of material elongation. An adequate interpretation of this law is given indicating that it touches only changes of magnitudes which describe the considered reality. The plot of elongation curve has been presented by separating a series of proper zones connected...
