$($ pipe length $=400$ m $,$Pipe D E $=180$ m $$diameter $=0.5$ m $,$friction factor is f $=0.03)$

Q$3.$ Given that the valve is open and the straight pipe was moved $($up or down!!$)$: if the velocity of the pipe is $2\mathrm{.}5$m$/$s$,$ find the absolute and gage pressure of water at the new elevations. The friction fctor is found using Moody chart for a pipe with a $0\mathrm{.}26$mm roughness
