Question $(1)$

Using the Moody diagram to determine the following properties:

$($a$)$ For a segment of a pipe, $=0\mathrm{.}06mm,D=5cm,V=4\frac{m}{s},$ and $v=6{10}^{-6}\frac{m^2}{s}.$

Find the fiction factor $f$ and the fully rough friction factor $f_T$

$f=$

$f_T=$

$($b$)$ For the following friction factors $(f)$ and Reynolds numbers $(R_{eD}),$ classify the

flow regime as laminar, transitional $($critical$),$ transitionally turbulent $($or rough$),$ or

fully turbulent $($or rough$).$ If a value is cannot be determined, indicate "not known"

or $"$NK$"$
