What is Reynolds in the eng.friction-factor?

Dimensionless ratio predicting flow regime. Below 2,300 = smooth laminar flow. 2,300–4,000 = transitional. Above 4,000 = turbulent.

What is Roughness Mm in the eng.friction-factor?

Reference formula or conversion factor shown for context.

Internal diameter of the pipe. Larger diameter reduces velocity and pressure drop but increases material cost.

A dimensionless multiplier applied in the calculation.

Sample size or count used in the calculation.
