Extracted text: An inward flow radial turbine shown in the figure below has a nozzle angle, a, of 60" and an inlet rotor tip speed, U, of 2 m/s. The ratio of rotor inlet to outlet diameters is 1.5. The absolute velocity leaving the rotor at section (2) is radial with a magnitude of 12 m/s. The temperature of the fluid is 20 °C. Section (1) Vz = 12 m/s Section (2). (a) Determine the energy transfer per unit mass of fluid flowing through this turbine if the fluid is air. N-m/kg Wair (b) Determine the energy transfer per unit mass of fluid flowing through this turbine if the fluid is water. N-m/kg Wwater
