5.1.6. A pump impellor 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 impellor is rotated at an angular speed of 450 rpm, water exits from the impellor with an absolute velocity of 45 m/s. The angle of the exiting water dois 35°. Determine the torque generated by the exiting flow. Hint: Torque of exiting flow: T = pQroVocos(a.)
