Friction Head Loss:6.556mm H2Om H2Oft H2Oin H2OpsibarPa Fluid Velocity:6.631mm/scm/sm/sft/sin/s Reference With fluid flows, the viscosity of the fluid around the surface of a pipe or duct causes loss of pressure ("head"); this is what we mean by friction loss. ...
(e.g. m3/s). The Moody friction factor (f) is used in theDarcy-Weisbach major loss equation. Note that for laminar flow, f is independent of e. However, you must still enter an e for the program to run even though e is not used to compute f. Equations can be found inDiscussion...

Colebrook Friction Loss Formula for Round Ducts In the region of laminar flow (Reynolds numbers less than 2300),the friction factor is a function of Reynolds number only. For completely turbulent flow (fully rough), the friction factor depends on duct surface roughness and internal protuberances ...
