Problem #$8$: $(22)$

Give the value of Reynolds number obtained with Moody diagram. The factor friction is $0\mathrm{.}03,$ is $0\mathrm{.}018$ mm $,$ and an area of $0\mathrm{.}1590c{m}^2.$ Show the solution in the Moody diagram.

$A=\frac{D^2}{4}$

Assuming ethanol as the fluid, determine the velocity in $\frac{m}{s}.$ Data: $=1\mathrm{.}1cP,$ density
