Question: Applied Hydraulics # 3 . 7 . 7 . A 2 0 - year - old, cast - iron pipeline is 3 , 8 0

Applied Hydraulics #3.7.7.
A 20-year-old, cast-iron pipeline is 3,800m long with a diameter of 40cm. The original Hazen-Williams coefficient was 130. A lot of tuberculation has occurred since it was installed. Flow tests are run to determine the existing CHW. A pressure drop of 232kPa is measured over the horizontal pipeline length for a flow rate of 0.176m3s. Determine the existing Hazen-Williams coefficient. Assume that minor losses are negligible and verify your results with computer software.
