Q4. Table Q4 shows experimental data gathered from propeller turbin running at full open condition. Table Q4. | At propeller turbine guide vane setting of 100% Turbine Speed (rev.min-1) Apl Delivary (bar) pressure P4 (KPa) Flow Hydraulic Power Turbine Shaft Turbine Rate (m3.s-1) (W) Efficiency Power (W) 0.25 0.38 0.24 0.38 0.24 0.38 0.24 0.38 0.24 0.39 0.24 0.39 0.24 0.4 1200 1100 3 1000 7. 900 8. 800 8. 700 8 600 500 0.23 0.4 0.23 0.4 0.23 0.4 0.23 0.41 400 9. 300 8 200 6. (a) Complete the table and plot turbine shaft power (vertical axis) vs. speed on a graph (horizontal axis). (b) Explain the effect of speed on shaft power and the speed at which maximum power is achieved. Make a graph that compares efficiency (vertical axis) with speed (horizontal axis) (horizontal axis). (c) (d) Explain the influence of turbine speed on turbine efficiency and the speed at which the maximum efficiency is achieved. Why is this turbine's efficiency so poor when compared to industrial turbines?
