Open Channel Flow ExperimentLab Report0904974This experiment investigated the area/velocity method and turbine flow meter method of calculating flow rate. Its aim was to compare accuracy and practical usage for each method. Initial hypotheses predicted that the turbine flow meter would have a higher level of accuracy than the area/velocity method. This was confirmed by the results. It was concluded that for high accuracy a turbine flow meter would be better suited however as it can only be installed within a pipe it would be unsuitable for many natural environments such as a river.IntroductionOn the 29th October 2013 an open channel flow experiment took place within the university lab. During this experiment the flow rate was measured in a tank using two methods. These were the area/velocity method and the turbine flow meter method. The purpose of this was to gather results to compare the accuracy and analyse the potential benefits and drawbacks of each method.Initial hypotheses were that the turbine flow meter would be more accurate as there are few opportunities for human error whilst conducting the experiment.Risk AssessmentA risk assessment was completed before the experiment began. This was discussed by the group and lecturer present. Everyone was made aware of the health and safety protocols should Any incidents occur.Materials and MethodSee Appendix 1Data and ResultsShown in Figure 1 are the results found by completing each experiment and completing the calculations to obtain the total flow rate. These are then plotted on the graph in Figure 2.
