Friction Factor Chart / Moody ChartFriction Factor For Laminar FlowCritical Flow ConditionThe friction factor or Moody chart is the plot of the relative roughness (e/D) of a pipe against the Reynold's number. The blue lines plot the friction factor for flow in the wholly turbulent region of the chart, while the straight black line plots the friction factor for flow in the wholly laminar region of the chart. In 1944, LF Moody plotted the data from the Colebrook equation and the resulting chart became known as TSee more on pipeflowpolyethylene pipe coefficient of frictiouhmw polyethylene coefficient of frictioncoefficient of frictioncoefficient of friction table plasticsuhmw coefficient of friction tablecoefficient of friction formulacoefficient of friction valuesabs plastic coefficient of frictionfriction coefficient stainless steelHDPE versus PVC PIPE - HydrogoldJan 05, 20129.3 Both PVC and HDPE pipes ofte n need to be de-rated for temperatures.
