The Swamee and Jain formula for the friction factor is

\[ f=\frac{0.25}{\left[\log \left(\varepsilon / 3.7 D+5.74 / \mathrm{Re}^{0.9}\right)\right]^{2}} \]

Compare this equation for \(\varepsilon / D=0.00001,0.0001,0.001\), and 0.01 and Reynolds numbers of \(10^{4}, 10^{5}, 10^{6}\), and \(10^{7}\) with the Moody chart and decide whether it is an acceptable replacement for the Colebrook formula.
