The mean blade radii of the rotor of a mixed flow turbine are0.3 mat inlet and0.1 mat outlet. The rotor rotates at20,000 rev/minand the turbine is required to produce430kW. The flow velocity at nozzle exit is700 m/sand the flow direction is at70° to the meridional plane. Determine the absolute and relative flow angles and the absolute exit velocity if the gas flow is1 kg/sand the velocity of the through-flow is constant through the rotor.
