Question:
Von Karman suggested that the wholly turbulent friction factor be expressed by the equation
\[ f=\frac{1}{4[0.57-\log (\varepsilon / D)]^{2}} \]
where \(\varepsilon\) is the absolute roughness of the pipe. Compare the values predicted by this equation and those indicated on the Moody chart.
