FFRANCIS TURBINE QUESTIONS & DISCUSSIONS 7. 1 QUESTIONS 1. Plot a graph of a. Turbine pep pill versus f base stride. b. Turbine drive oning versus end product torque. c. Turbine fastness versus hydraulic power. d. Turbine swiftness versus automatonlike power. e. Turbine velocity versus efficiency. 2. Give your comment(s) from the graph obtained. ? Based on the graph Turbine velocity versus flow rate, it is shown that debate for both z=50% and century%is increasing when turbine velocity increase, flow rate also increasing. From the graph Turbin velocity versus output torque, it is shown that output torque for the both crinkle testament increase slightly when turbine velocity is increase ? In the Turbin velocity versus hydraulic power graph,the line shows pissing speed is increasing due to increasing of hydraulic power. Overall, when turbine velocity become large therefore it will increase hydraulic power. ? graphical record of Turbin velocity versus mechanical power s hows mechanical power increase when turbine velocity is departure down. ? For the graph of Turbin velocity versus efficiency, it shows its efficiency diminution when turbine elocity increase. 3. State phoebe bird (5) safety factors that decl ar been taken in the prove. There is five safety factors that should be taken temporary hookup doing the experiment in laboratory ? subscribe to sure our hands are dry out when switch on the switch of the form ? stir sure the turbine is not halt immediately as it tends to overspeed with emergency stops. ? Make sure the equipment function salutary before experiment get started. ? Must note procedure going on the experiment so accident could be stay off during experiment. ? Make sure handling well the equipments during experiment and void silly behavior.DISCUSSIONS Francis turbine is a type of weewee turbine that was developed by James B. Francis. It is an inward flow reception turbine that combines radial and axial flow concepts. Francis turbines are the close common water turbine in use today. They operate in a head range of ten meters to several(prenominal) hundred meters and are primarily use for electrical power production. In certain life, the basic operating system of the Francis Turbine is employ to generate hydroelectric power. To design the most efficiency hydroelectric generator, several factors -head, low rate, velocity, power and efficiency of the area should be taking into account. Hman is the differences of blackmail head sight which measured the pressure and the turbine shaft bar. It is a kinetic parameter which cause by water velocity. The height differences between the pressure gauging point position and the point of water level at the outflow of credit will influence the power of outlet. demean river flows because of drought, climate change or upstream dams and diversions will reduce the amount of cognise storage in a seed therefore reducing the amount of water that can be used for ydroelectricity. The resolving of diminished river flow can be power shortages in areas that depend heavy on hydroelectric power. The turbine overall efficiency, is compute as the ratio of power at outlet point compared to the generated power. It is because in essential the head and velocity of water source is not possible remaining constant. It will influence capacity factor reject than 100%. During the experiment, there big businessman be some error that affects the result of this experiment. The errors that might occur are parallax error age recording the readings or inaccurate period counting.Besides, before starting the experiment, the water jimmy of the tank storage should be check over for remaining at acceptable water lever. CONCLUSION From the experiment that was done, we can answer that the turbine velocity is increase with the flow rate, output torque, and hydraulic power but belittle in efficiency and mechanical power.
