Question

A rotating nozzle spins at 1500 rpm and measures 1-m in diameter. If air enters the base at 4.6kg/s and exits at the pipe ends at 350 m/s relative to the pipe, calculate the frictional moment in the bearings M 0.5 m -1500 rev/min 0.5 m 0.482 kN-m O 620 N-m 0 158 N-m O 40 kN-m O 336 N-m O 3.36 kN-m 0 4.82 N-m O 0.896 kN-cm 123 N O 896 N-m
