Thrust Bearing design 1. You have been asked to design a minimum power-loss‚ uni-directional‚ thrust bearing for an horizontally-mounted‚ axial‚ ammonia compressor in a nitric acid plant. The compressor has a shaft diameter of 100 mm and generates a thrust of 15kN when operating at 6‚000 rpm. The thrust is negligible at zero speed. a. What type of thrust bearing would you recommend and why? b. What are the physical reasons why a dry‚ PTFE bearing would be unacceptable? c

Weighting of items can improve validity of a checklist‚ which can affect which trainees pass or fail (Sandilands
