Transcribed Image Text:07. An inward flow radial turbine involves a nozzle
angle, a, of 60° and an inlet rotor tip speed, Ur, of 9 m's.
The ratio of rotor inlet to outlet diameters is 2.0. The
radial component of velocity remains constant at 6 m/s
through the rotor, and the flow leaving the rotor at
section (2) is without angular momentum. If the flowing
fluid is water and the stagnation pressure drop across the
rotor is 110 kPa, determine the loss of available energy
