RESULTS For different flowrates, we measure the pressure drop in specified parts of the rough pipe with, flow nozzle, orificemeter, pitot tube and manometer in this experiment. Our data obtained from the experiment is given in the data sheet. For sample calculation we take the first data. The mass flowrate is calculated from the time needed to fill the bucket. The mass of the water – filled bucket is known so; kg m 690 , 14 = (water – filled bucket) s t 54 = (time cosumed to fill the bucket for the first run) s g t m m 272 54 690 , 14 = = = (Eqn3.1) The corresponding mass flowrates for the other data are calculated with the same procedure and found values are given in the table. Table 3.1 Corresponding mass flowrates to the each experiment run Time Needed To Fill(s) Mass Flowrate(g/s) 1 st Run 54 272 2 nd Run 56 262.3 3 rd Run 66 222.5 4 th Run 78 188.3 5 th Run 90 163.2 6 th Run 110 133.5 7 th Run 164 89.6 Orificemeter Calibration In here it is needed to plot lnm & lnh graph. For that reason, the experimentally found values are converted into ln values. The results are shown in the Table3.2 the corresponding graph is drawn in Figure3.1.
