Water is pumped through a 60-m-long, 0.3-m-diameter pipe from a lower reservoir to a higher reservoir whose surface is 10 m above the lower one. The sum of the minor loss coefficient for the system is K_L = 14.5. When the pump adds 40 kW to the water the flowrate is 0.20 m³ /s. Determine the pipe roughness.
