Inner diameter (I.D.) is the span of the empty space in a circular hose cross-section that affects the flow velocity of the fluid within the hose. A hose with an oversized I.D. will result in sluggish system performance, while an undersized I.D. can cause excessive pressure drops, leaks, and system damage.

#### Pressure Loss from Fittings - Expansion and Reduction in …

There are two components to the pressure loss/gain through an area change, the permanent pressure loss and the change due to acceleration. As the name suggests the permanent pressure loss is not recoverable, and like the pressure loss through ordinary fittings such as a pipe elbow, it is lost to friction, eddies, and noise.
