b)An inward flow reaction turbine works under a head of 100m. The inlet and outlet diameters of the runner are 1.2 m and 0.6 m, respectively. The width of the runner is 150 mm, which is constant throughout. The velocity of flow at the outlet is 6 m/s. The blade angle at the outlet is 15. The hydraulic efficiency is 0.9. Calculate the following: ) The speed of the Turbine...

A turbine designer is trying to select the appropriate blade shape to generate power efficiently. Based on the inlet and outlet structure of the device, they know that the absolute fluid velocities, V1 and V2, are oriented as sketched below: At the inlet radial position, R1, of 2.4 m, the velocity, V1, is 18 m/s at an angle, 01, of 55° relative to the circumferential direction. At the outlet radial position, R2, of 1.3 m, the velocity, V2, is 8.4...

The centrifugal pump as described in Q5.8 is operating with a pre-whirl of 10° (i.e. Ui is inclined by 10° from the radial axis in the rotational direction). The centrifugal pump delivers 0.45 m3/s ofwater when it is running at the angular velocity of ω-1200 rpm Sketch the velocity triangles at inlet and exit of the impeller and hence determine the following items by assuming (a) negligible losses; and (b) Vi enters the impeller with θ| and V2 leaves with...

(b) A centrifugal pump rotates at 750 rpm. Water enters the impeller normal to the blades (GJ 0°) and exits at an angle of 35° from radial (α,- 35°). The inlet radius is r12.0 cm, at which the blade width bi 18.0 cm. The outlet radius is r2 24.0 cm, at which the blade width b 16.2 cm. The volume flow rate is 0.573 m/s. Assuming 100 percent efficiency. Given density of water to be 998 kg/m3 i Calculate the...
