👉 A closed fluid is a type of fluid system where the volume remains constant and there is no exchange of fluid with the surroundings. This means that the fluid inside the system is completely contained within a defined boundary, and no fluid can enter or leave through any opening or connection. In practical terms, this is often seen in sealed tanks, pipes, or containers where the fluid's pressure and volume are maintained without any loss or gain. The behavior of a closed fluid is governed by principles such as Pascal's Law and the conservation of mass, making it crucial in various engineering applications like hydraulic systems and pressure vessels.
