- Thermodynamics is a branch of physics that deals with the study of energy and its transformations in various forms, including heat, work, and internal energy. It is concerned with the behavior of macroscopic systems and their properties, such as temperature, pressure, volume, and entropy.
- The second law of thermodynamics is a fundamental principle in physics that governs the behavior of energy and its transformations in various forms. It states that in any natural process, the total entropy of a closed system always increases over time, or remains constant in the idealized case of a reversible process.
- A vapor power cycle is a thermodynamic cycle that involves the conversion of thermal energy into mechanical work through the use of a working fluid that undergoes phase changes from a liquid to a vapor and back. The basic components of a vapor power cycle include a boiler, a turbine, a condenser, and a pump. The cycle typically operates on a closed loop, with the working fluid being continuously recycled through the system.
- Refrigeration and air conditioning are processes that involve the transfer of heat from one location to another for the purpose of cooling or maintaining a desired temperature. Refrigeration is the process of cooling a space or substance to below the temperature of its surroundings, while air conditioning is the process of cooling and dehumidifying the air in an area.
- A gas power cycle is a thermodynamic cycle that involves the conversion of thermal energy into mechanical work through the use of a gas that undergoes a series of processes. The essential components of a gas power cycle include a compressor, a combustor, a turbine, and a heat exchanger. The cycle typically operates on an open loop, with the working fluid being continuously supplied from an external source.
- Internal Combustion (IC) Engines is a process that involves burning a fuel mixture inside an engine in order to produce mechanical energy. In an internal combustion engine, fuel and air are mixed together in a combustion chamber, where they are ignited by a spark or by compression. This produces a rapid expansion of gases, which pushes against the engine's pistons, causing them to move and generate rotational energy.
- Materials are substances that are used to make objects, tools, structures, and other products. They can be naturally occurring or synthetic, and they come in a variety of forms, including solids, liquids, and gases. Materials can be classified based on their properties and characteristics, such as their physical, chemical, and mechanical properties.
- The manufacturing process refers to a series of steps or operations that are used to transform raw materials into finished products. The manufacturing process can vary depending on the type of product being produced.
- Power transmission refers to the process of transmitting electrical power from one location to another. It involves the use of transmission lines, transformers, and other equipment to transfer electricity from power plants or other sources to homes, businesses, and other electrical loads. The transmission system may operate at high voltages and long distances to reduce energy losses and increase efficiency.
