The steady flow energy equation is a fundamental concept in thermodynamics, used to analyze the energy interactions in steady-state fluid flow systems. This equation states that the total energy entering a control volume equals the total energy leaving the control volume, accounting for energy transfers as heat and work. Mathematically, it is expressed as: h1 + ke1 + pe1 + q = h2 + ke2 + pe2 + w, where h represents specific enthalpy, ke is kinetic energy, pe is potential energy, q is heat added, and w is work done by the fluid. The steady flow energy equation is widely applied in the analysis and design of various engineering systems, such as turbines, compressors, heat exchangers, and pipelines. By applying this equation, engineers can determine energy changes, calculate work and heat transfer rates, and optimize system performance. The steady flow energy equation provides a powerful tool for understanding and predicting the behavior of fluid flow systems.
