A pump impeller has an outside radius of 50 cm, an inside radius of 15 cm, and vanes with a uniform opening (width) of 20 cm. When the impeller is rotated at an angular speed of 450 rpm, water exits from the impeller with an absolute velocity of 45 m/ sec. The angle of the exiting water is 55 degrees measured from a radial line emanating from the center of the impeller outward. Determine the torque generated by the exiting flow.
