long and $5\mathrm{.}5-$cm$-$diamcter horizontal pipe made of stainless steel at a rate of $9\mathrm{.}8$ Us$.$ Determine

$($a$)$ the pressure drop. $($b$)$ the head loss, and $($c$)$ the pumping power requirement to overeome this

pressure drop. $($d$).$Compare the head loss calculated in $($a$)$ with the equation of Swamee$$and$$Jain$.$
