Question description

The impulse-turbine system shown in Figure 8.55 uses water at 20◦C from a reservoir with a water-surface-elevation that is 80 m above the elevation of the nozzle. The length of the 300-mm delivery pipe is 600 m, and the delivery pipe has an estimated roughness of 0.5 mm. The nozzle at the end of the pipe is estimated to have a nozzle-loss coefficient of 0.05, and the buckets on the impulse turbine have a deflection angle of 160◦ . (a) Identify the optimum nozzle diameter, and state the corresponding power that can be extracted by the turbine. (b) Determine the optimum nozzle diameter and corresponding power derived by assuming fully turbulent flow in the supply pipe, and compare your result with that obtained in Part (a). Comment on the appropriateness of assuming fully turbulent flow.
