WebAug 8, 2010 · For fitting y = Ae Bx, take the logarithm of both side gives log y = log A + Bx. So fit (log y) against x. Note that fitting (log y) as if it is linear will emphasize small values of y, causing large deviation for large y. This is because polyfit (linear regression) works by minimizing ∑ i (ΔY) 2 = ∑ i (Y i − Ŷ i) 2. WebYou can use curve--fitting equations and software such as Excel to approximate the Moody diagram’s output. Don’t confuse the Darcy friction factor with the Fanning friction factor — the Darcy friction factor is by definition four times the Fanning friction factor. If you do decide to use a Moody diagram to find the friction factor, be ...
