👉 Eolipile is a mathematical concept in physics and engineering related to the study of fluid dynamics. It refers to a type of fluid that flows parallel to its own axis, without any resistance from other fluids or objects. In fluid mechanics, an "eolipile" is a flow pattern where the velocity vector (the tangential component of the flow) is always perpendicular to the plane of motion, and this direction is called the "eolipole" axis. This property makes it
