  4. Additionally, X-ray photoelectron spectroscopy and Raman spectrum analysis revealed that the reason for the low coefficient of friction of Hf-Ag-N solid solution coating is mainly due to the large number of tribo-oxidation products (HfO 2, Ag 2 O) and self-lubricating phase (Ag) on the worn surface. The density functional theory further ...

  5. The friction factor in the Darcy-Weisbach Equation is a dimensionless quantity that represents the resistance to flow due to friction in a pipe. It is determined experimentally and varies with the Reynolds number and the roughness of the pipe surface.

  6. Weisbach first proposed the relationship that we now know as the Darcy-Weisbach equation or the Darcy-Weisbach formula, for calculating friction loss in a pipe. Darcy-Weisbach equation: hf = f (L/D) x (v^2/2g) where: hf = head loss (m) f = friction factor L = length of pipe work (m) d = inner diameter of pipe work (m)
