Sentence examples for Roughness height from inspiring English sources

The relative roughness height was 0.123 and the relative roughness pitch was 12.5.

Variation in roughness height along the considered bed feature is also discussed for a particular experiment.

The pressure gradient over the horizontal bend increases gradually with the increase of roughness height.

The pressure drop is much smaller when the roughness height is zero.

The Reynolds number, relative roughness pitch (P/e) and relative roughness height (e/D) are chosen as design variables.

The influence of roughness becomes increasingly important when the roughness height lies in the fully turbulent regime.
