Water at $18\backslash$deg C Rows through a $25-$m$-$long, $75-$mm$-$diameter commercial stee! pipe that contains the following fittings: one open angle valve, one short$-$radius elbow, and one $90\backslash$deg pipe bend $($ko $=0\mathrm{.}12)$ with a radius of curvature of $60)$ min The length of the bend is not included in the $25$ m$.$ There are no entrance or discharge losses. Find the total head loss if the flow velocity is $2$ m$/$s$.$
