I know for a fact that you can use both manning and hazen willmias for both open channels and pipe flow systems even though common practice is to use hazen william for pipe flow and manning for open channel but does anyone know why this is the common practice? What are the different assumptions made ? What makes manning's more acceptable for open channels and hazen williams more acceptable for pipe systems?
Thank you, just a correction: as per the formula k is a conversion factor for the unit system (k = 1.318 for US customary units, k = 0.849 for SI units).
I disagree that the Moody diagram can’t be programmed. I have done it several times in the past in Excel VBA and C using Darcy - Weisbach and Colbrook forms. I may be wrong but I think Hazen- Williams is limited to water and in Industry we run into many other fluids.

Appreciate this video. Just needed to understand headloss. This explained it perfectly in line with the Hazen-Williams Equ. Thank you
thanks for catching that mistake everyone, yes I should have used K1 = 1.318 all along for that problem
@A00363800 he replaced the correct K1 (K1=1.318) on the equation for V if you check it at 6:10!
Great video. I worked it out. I used Mathcad. As some posts already indicated, C for the example should be 0.848.

where can I find a graphical solution for the Hazen Williams formula
In your example finding Q, you said K1 = 0.849 was for SI units. What is correct?

He shud put m/s insteady
