2.2 A 250 mm diameter pipe is 1500 m long. When the discharge is 0.095 m3/s in this pipe, the pressure drop between the ends of the pipe is measured as 98.06 kPa. The elevation at the end of the pipe is 10 m below its beginning. What type of flow is this? What is the equivalent sand-grain roughness of the pipe wall? What is the Hazen-Williams roughness coefficient? How much energy is dissipated by fluid friction during each hour that this flow continues? Use v = 1.31xlO- 6 m2/s.
