Fluid machinery refers to devices that move fluids, such as liquids and gases, to perform work. Common examples include pumps, which transport liquids, and turbines, which convert fluid energy into mechanical energy. These machines are essential in various industries, including power generation, water supply, and manufacturing, helping to efficiently manage and utilize resources. The design and operation of fluid machinery rely on principles from fluid dynamics and thermodynamics. Engineers use these principles to optimize performance, ensuring that machines operate effectively and sustainably. Understanding fluid machinery is crucial for advancements in technology and improving systems that rely on the movement of fluids.
