Pipe Diameter, $D=0\mathrm{.}15m($suction and discharge pipe diameter same$)$

flowrate $=0\mathrm{.}06m\frac{3}{s}$

total pipeline length $($suction $+$ discharge$)=50m$

Minor head losses $=13\mathrm{.}7m$

$($elbow$,$ valve, exit, etc$)$

$10$ torr $($vacuum$)=10\mathrm{.}2m$ head

$1$atm$=10\mathrm{.}3m$ head

a$)$ Calculate the friction loss of the pipe $($suction $+$ discharge pipe$).$ Only piping friction loss exclude minor losses from pipe elbow, valve, etc

assume friction factor, $f=0\mathrm{.}023$

b$)$ Calculate the total dynamic head in unit $m.$
