##### The Moody chart cannot find $V$ directly, since $V$ appears in both ordinate and abscissa. (a) Arrange the variables $\left(h_{f}, d\right.$ $g, L, \nu)$ into a single dimensionless group, with $h_{f} d^{3}$ in the numerator, denoted as $\xi,$ which equals $\left(f \mathrm{Re}_{d}^{2} / 2\right) .$. $(b)$ Rearrange the Colebrook formula (6.48) to solve for $\operatorname{Re}_{d}$ in terms of $\xi .(c)$ For extra credit, solve Example 6.9 with this new formula.
