Cihan YILMAZ 030010099 Determining the Pipe Friction Loss and Local Losses through a Closed Pumping System Introduction Pipe friction loss test is a closed loop arrangement that includes a straight, long pipe fed by centrifugal pump, which sucks water from a tank. Head loss measurement is to be performed using a differential manometer connected to both sides of a unique piece of galvanized pipe. Local loss experiment includes a kind of piping system that goes out from a tank and have several minor loss components such as sudden contraction, expansion, elbos, valves, venturi- meters, orifice on the suction side of the pump. Fifteen piezometric tubes are placed on to appropriate points on the suction side of the in order to measure piezometric heads along the flow path. The flow-rate will be determined by counting optically the flow per unit time using a chronometer. Purpose of the experiment 1. To obtain experimental data of the Darcy-Weisbach pipe friction loss coefficient, λ with respect to non-dimensional Re number in turbulence flow. 2. To see whether the experimentally derived friction factor is consistent with published values and to determine whether the variation of λ with the Reynolds number is consistent with variations represented on the Moody diagram. 3.
