👉 Non-viscidly is a concept in fluid mechanics that refers to a fluid that has no tendency to flow or form a viscous structure. This means that even when subjected to external forces, such as pressure or temperature changes, it does not experience any shear stress or deformation. In other words, the fluid remains incompressible (i.e., its volume does not change with respect to its thickness) and behaves like a liquid under these conditions. Non-viscous fluids are often used in applications
