Consider a cylindrical rotating machine where the rotor rotates at a rate of 900 rev/min. Air enters the engine at a rate of 11300 L/s from a radial distance of 75cm and exits with a radius equal to 1.3m. The angle of inclination of the flap is 30 ° and the height of the flap is 40 °. If the blade output angle is adjustable, at what output angle range will the engine act as a turbine?

Consider a cylindrical rotating machine where
the rotor rotates at a rate of 900 rev/min. Air
enters the engine at a rate of 11300 L/s from a
radial distance of 75cm and exits with a radius
equal to 1.3m. The angle of inclination of the flap
is 30 ° and the height of the flap is 40 °.
If the blade output angle is adjustable, at what
output angle range will the engine act as a
turbine?
