Question 1 A pipeline 30 m long connects two tanks which have a difference of water level of 12 m. The first 10 m of pipeline from the upper tank is of 40 mm diameter and the next 20 m is of 60 mm diameter. At the change of section, a valve is fitted. Calculate the rate of flow when the valve is fully opened assuming that its resistance is negligible and that f for both pipes is 0.0054. In order to restrict the flow the valve is then partially closed. If k for the valve is now 5.6, find the percentage reduction in flow. Note the following Reservoir I Segment of Length Pipeline B Diameter (m) (mm) ABC AB 10 40 BC 20 60 Head loss due to friction h₁ = KQ² Valve fl K = 3.028D' Where, •h₂ = k Head loss due to partial closure (VAB-VBC) 2g Reservoir 2 H-12 m

Civil engineering students performed an evaluation of the two primary methods of classification (supervised and unsupervised). The evaluation of the two methods utilized the error matrices. Tables 1 and 2 represent supervised and unsupervised methods respectively.
