What is friction factor ?

The friction factor is a dimensionless number that quantifies the resistance to flow within a pipe or channel due to surface roughness and fluid viscosity. It's crucial in calculating head loss and energy dissipation in fluid systems, influencing flow efficiency. The friction factor is typically determined using the Darcy-Weisbach equation or empirical correlations like the Moody chart, depending on flow conditions such as Reynolds number and relative roughness.
