- Water enters a perforated irrigation pipe (Length L, diameter D) with a uniform velocity Uin=10m/s. The water exits at the outlet with an average velocity Uout =8m/s and through N=10 perforations that all have the same diameter (d). The perforations are distributed at equidistant lengths, with the first one and last one located at a distance lo from the inlet and the outlet, respectively. It will be assumed that the average velocity through the perforations decreases linearly as one moves down the perforations. The flow rates through the different perforations have to be controlled to ensure proper irrigation of different plants.
