By using Moody's chart this chart, engineers can predict the friction caused by the pipe's surface on the fluid flowing through it. This helps in determining pressure drop or flow rate.The chart plots the Darcy-Weisbach friction factor fD on the y-axis against the Reynolds number Re on the x-axis. Multiple lines are included representing various relative roughness values (ε/D). The chart can be broadly divided into two flow regimes: laminar and turbulent. In the laminar zone (Re is less than ~3000) the pipe roughness has minimal impact, and the friction factor can be calculated analytically. However, in the turbulent zone, the relationship between these factors is more complex. By this short and lucid lecture and a numerical, one can learn easilly how to find the friction favtor of pipe by the help of Moody's chart.
