### Screening Efficiency an overview ScienceDirect Topics

May 01, 2012The influence of internal friction (b⁎) resulting from relative motion between the solid skeleton and the pore fluid is investigated in Figs. 5.1.4 and 5.1.5, by varying values of b⁎ (b⁎ = 0, 5, 50, and 500).Recalling b⁎ is inversely proportional to the permeability, it suggests that the material with b⁎ = 0 is the most permeable, and the material with b⁎ = 500 is the least

### Efficiency Formula Softschools

Efficiency is a measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage. A perfect process would have an efficiency of 100%.
