Step-by-step calculations for series and parallel piping systems. Also includes correction factors for non-Newtonian fluids (pseudoplastic, dilatant, Bingham plastics). hf=f⋅LD⋅v22gh sub f equals f center dot the

hf=f⋅LD⋅v22gh sub f equals f center dot the fraction with numerator cap L and denominator cap D end-fraction center dot the fraction with numerator v squared and denominator 2 g end-fraction = Friction head loss (feet or meters) = Darcy friction factor (dimensionless) = Length of the pipe (feet or meters) = Internal diameter of the pipe (feet or meters) = Mean fluid velocity (feet/second or meters/second) = Acceleration due to gravity ( 2. The Colebrook-White Equation To determine the Darcy friction factor (

Piping systems are rarely straight lines. Every bend, valve, tee, and reducer disrupts the fluid velocity profile, causing localized turbulence and additional head loss. These are known collectively as "minor losses," though they can often exceed straight-pipe friction losses in complex plants.

From the manual’s dimensional data table (Appendix A): 6-inch SCH 40 steel has ID = 6.065 inches (0.5054 ft).
