The single-stage, axial-flow turbomachine shown in Fig. P12.52 involves water flow at a volumetric flowrate of \(9 \mathrm{~m}^{3} / \mathrm{s}\). The rotor revolves at \(600 \mathrm{rpm}\). The inner and outer radii of the annular flow path through the stage are 0.46 and \(0.61 \mathrm{~m}\), and \(\beta_{2}=60^{\circ}\). The flow entering the rotor row and leaving the stator row is axial when viewed from the stationary casing. Is this device a turbine or a pump? Estimate the amount of power transferred to or from the fluid.
