Given: An inward flow radial turbine involves a nozzle angle, a₁, of 60° and an inlet rotor tip speed, U₁, of 6 m/s.The ratio of rotor inlet to outlet diameters is 2.0. The absolute velocity leaving the rotor at section (2) is radial with a magnitude of 12 m/s.

Find: The power transfer per unit of mass of fluid flowing through this turbine.Ws/m
