Coefficient of Friction Si Unit
The SI unit of η is Newton-second per square meter Ns. V is velocity in fts for US customary units in ms for SI units k is a conversion factor for the unit system k 1318 for US customary units k 0849 for SI units C is a roughness coefficient. Friction Coefficients In Aci 318 71 08 1 Download Table It is expressed in Newtons N. . A Pipe cross-sectional area ft 2 or m 2. Hazen-Williams Coefficient C varies from approximately C60 for 40-year old cast iron pipe to C150 for new plastic pipe. Pascal-seconds Pa s Hence the coefficient of viscosity is a measure of the resistance of the fluid to deformation at a given rate due to internal friction. There are two easy methods of estimating the coefficient of friction. K1318 for English units feet and seconds. Unit of Coefficient of Viscosity. The Flow Factor k v defines the friction loss for water at a density of ρ1000kgm 3. It occurs when two objects are sliding ag
