A 230-m-long pipeline delivers 20◦C water to a storage reservoir located downstream. The pipeline is galva-nized with an average roughness height of 0.2 mm. An axial pump is used to pressurize upstream water. Thewater surface in the reservoir is located 18 m above the centerline of the pump. The pump discharges waterat an absolute pressure of 400 kPa and a volume flow rate of 50 L/s. Calculate a diameter of pipe requiredto achieve such an operating condition. If needed, use the Moody diagram on the last page, or one can solvethe Colebrook equation using, for example, Matlab.
