👉 Circumduct is a term used in physics and engineering to describe a system that has an external force applied to it, causing its internal forces (such as pressure or temperature) to change. This can occur due to changes in fluid flow rates, such as through friction between moving parts or the movement of fluids themselves. The concept of "circumduct" was first introduced by physicist John Archibald Wheeler and is often used in discussions of fluid dynamics and heat transfer. It refers to a
