Abstract A team consisting of five members conducted an experiment on a straight pipe section of a Manometer. During the course of the experiment the following values were found: Head lose as a function of volume flow rate and the friction factor as a function of Reynolds Number. Table 1 Flow Number Hanging Mass Time to collect ‘m’ kg Equivalent to ‘3m’ kg of water flow Calculate Mass flow Rate Piezometric readings between 3 and 4 1.) 6kg t 1 = 59.90s t 2 = 47.29s t 3 = 59.38s t 4 = 51.86s t 5 = 54.71s t avg = 55.23s .326 m/s 360 2.) 4kg t 1 = 37.06s t 2 = 38.29s t 3 = 30.18s t 4 = 30.60s t 5 = 36.28s t avg = 34.07s .352 m/s 360 3.) 8kg t 1 = 88.4s t 2 = 79.1s t 3 = 83.52s t 4 = 72.78s t 5 = 79.20s t avg = 80.6s .298 m/s 285 4.) 2kg t 1 = 16.70s t 2 = 18.56s t 3 = 19.94s t 4 = 19.27s t 5 = 18.88s t avg = 18.87s .318 m/s 350 5.) 2kg t 1 = 20.39s t 2 = 19.50s t 3 = 18.84s t 4 = 21.20s t 5 = 19.89s t avg = 19.98s .300 m/s 300

In order to obtain the results in table 1 the team conducted the following procedure: 1. Before any trial was actually run the team, a.) Made sure the hydraulic bench supply line was connected to the manometer, b.) Had at least one valve closed, c.) That all piezometric tubes indicated zero pressure, and finally d.) The bucket inside the hydraulic
