Question details

Exercise 2 A horizontal pipeline is attached to a reservoir. The pipeline has different profiles. The diameters and lengths of the parts of the pipeline are: Di 0.24 m, L1-3 m, D2-0.1, L21 m, Ds 0.12 m, L 2 m. The water level in the reservoir is 1.5 m above the axis of the pipeline and from the lower end of the pipeline water flows out in open space. a) Calculate the discharge Q using the Toricelli equation. Calculate then the flow velocity and the pressure in the three parts of the pipeline ignoring friction. b) Now consider all losses and calculate the discharge . For the minor losses one has: (1) inlet to pipeline: Kinlet 0.5 (2) contraction from D1 to D2 with D2/D1-0.417: Kcontr. = 0.35 (related to D2) (3) enlargement from D2 to Ds with Ds/D2 1.2: Kearg 0.19 (related to Ds) For the major losses one starts by assuming that there is completely turbulent flow. For slightly rusted pipes (e-0.5 mm) one can find the values for the three friction coefficients λ in the part of the Moody diagram for the completely turbulent regime (or for a maximal Reynolds number 108) Check your results with MATLAB and the Colebrook-White equation assuming a Reynolds number of 108 Inserting then all minor and major losses in the Bernoulli equation and expressing the velocities by the discharge Q, it is possible to obtain a value for Q c) Using the discharge Q calculated in b) allows then in a second step to verify the values of the coeficients A. For that one calculates the Reynolds numbers for the three parts of the pipeline (kinemtic viscosity of water: v 1.31 10-6 m2/s). And with the now known values for the Reynolds numbers, one once again determines the λ-values using the Moody chart and the Colebrook-White equation. Since the new values for the coefficients are not exactly the same as the initial values, recalculate Q. In this way it is possible to approximate Q iteratively. it is then necessaryPlease I need a complete step by step solutions asap. Its for my finals. Please explaine how you got the value on a moody diagram too. If necessary I can uplaod a moody diagram
