SPECIFIC ENERGY VS ISENTROPIC EFFICIENCY Efficiency losses at reduced rotational speeds is evident in certified Specific Power curves. The peak efficiency point is usually observed between 40%-to-50% of rated capacity. Efficiency decay accelerates below the peak. Screw compressors typically provide 60%-to-75% capacity rate turn-down from published maximum capacity ratings. Recently, in addition to publishing Specific Power values at various flow rates, Isentropic Efficiency calculations have been introduced. Mattei, applauds this transition as it eliminates pressure/flow variances to better...
