Abstract: In the theory of two-phase liquids, issues related to the processes of continuous addition (or detachment) from the outside with a liquid have been little worked out. Such problems are common in hydraulic engineering and water management systems. The study of hydrodynamic processes occurring in one- and two-phase fluids with a continuously changing flow is a very complex issue, since the change in the flow (mass) along the flow is one of the main factors affecting the motion of a two-phase system. This must be taken into account in the theoretical study of two-phase liquids and in solving practical problems. From this point of view, relevant topics are the derivation of the equations of motion of two-phase fluids, the construction of mathematical models, the development of modeling criteria and reporting methods. The purpose of this article is to derive the energy equations (kinetic, total). To reflect the process of energy transition from one form to another during the transport of a medium, the total energy balance equation for a two-phase continuous medium was obtained, obtained from the law of conservation of energy.
