Dec 29, 2016 Efficiency is defined by the ratio of output to input. For example, if a 100-hp motor drives a rotary table and produces 85 hp to rotate a drill string, the efficiency of the system is 0.85, or 85. Drilled solids removal efficiency would imply a ratio of output or discard to input circulating volume.
