Using Pipe-flo or Hydroflo to solve the following problem. (Report the results by including screenshoots )Water is pumped from a low reservoir to a high reservoir that is 20 m higher in elevation. The water is flowing at 1.5 m/s through a 305 mm internal diameter piping system. The water is at 18 degrees C. There are 1,000 m of piping, six standard 45 degree bends, two standard 90 degree bends, a branch flow tee, three gate valves, a swing check valve, a square inlet and a square outlet. The piping and valves are ductile iron, cement lined, with an absolute roughness Ꜫ of 1.0 mm due to chemical deposits. Use hand calculations and show all of your work. a. Calculate the Reynolds Number (NR), the relative roughness (Ꜫ/D), and Darcy’s “f”. b. Calculate the pipe friction loss in m using Darcy’s Equation. c. Calculate the minor losses (entrance, fittings, valves, exit) in m. d. Calculate the total losses (pipe friction plus minor losses) in m.
