Without more specific information about the impeller type and application, I was forced to be conservative, but reasonable.
Minimum motor size = 140 kW
Minimum shaft diameter = 163 mm
Minimum torque = 22,200 N-m
Minimum bending moment = 25,200 N-m
Bearing size will depend on spacing between bearings, but can be sized from the torque and bending loads.
