Extracted text: 4. Given a portion of a water supply pipe network system below. Determine the actual flow in each pipe and the respective head losses. Assume flow in pipes AB and BC in loop Il and I respectively equal to 0.142 m3/s clockwise and 0.038 m3/s clockwise for the first trial. Use Manning's Equation with n 0.011. %3D Pipes АВ Length (m) 700 Diameter (cm) 30 ВС 800 15 CD 1100 25 DE 650 35 300 1500 EA 10 BD 10 Q, = 0.15 m/s %3D QA = 0.10 m/s Qc = 0.10 m/s В Loop I Loop II E A Q = 0.15 m/s %3D
