Abstract: Thermodynamics has solved heat-transfer problems for mechanical and chemical engineering both in the case of laminar and turbulent flow in closed conduits and in boundary layers, by simultaneously applying continuity, movement and energy equations. Some difficulties emerge in the course of its application in hydraulic engineering, because velocity-distribution and boundary conditions are irregular, and also because the changes in the turbulent diffusion factor must be taken into account. The main fields in the hydraulic engineering application are the flow in closed conduits or between two plates and solutions for turbulent flow and heat transfer in boundary layers under certain assumptions, which whether fulfilled or not, must be judged for each particular problem. The study makes a comparison of the natural and ideal state and tries to point out the possible applications of the heat-transfer relationships.
