Can clamps or supporting clips smaller than the outside diameter of the hose restrict fluid flow?

When considering the relationship between clamps or supporting clips and the hose they are designed to support, it's important to understand how they interact with the fluid flow within the hose. Clamps that are smaller than the outside diameter of the hose can indeed restrict fluid flow. This restriction occurs primarily because a smaller clamp may apply undue pressure on the hose, leading to deformation or constriction.

If the hose is pinched or compressed in certain areas due to the clamp being too small, the internal diameter of the hose will be reduced, which directly impacts the cross-sectional area available for fluid to flow through. This can lead to increased resistance and decreased flow rates, potentially impairing the functionality of the system. Additionally, if the clamp constricts the hose unevenly, it can create turbulence, further complicating fluid dynamics. Therefore, the answer is true; such clamps can impede flow by physically altering the shape of the hose.
