Water is being from $1$ to $2$ using a pipe as shown below.

Elevation of $1(Z_1)=120m$

Elevation of $2(Z_2)=100m$

The pipe diameter $(D)=20cm$

The pipe length $(L)=$ According to No$.$ Student

The friction factor $(f)=0\mathrm{.}012$

L$=350$m

$1-$ Ignore minor losses.

$2-$ Calculate $($manually$)$ the velocity $(V),$ head loss $)$ for different flow rates $($Q$).$ Present your results in a table like:
