Expansion of the Equivalent Entropy Drop Method

YAN Shui-bao,WANG Qiu-hong (North China Institute of Water Conversancy and Hydraulic Power,Zhengzhou 450045,China)  
Doing work capacity of work substance in thermodynamic system depends on position that work substance locates on, and is not relevant on how work substance reaches the position. Relation of two equivalent entropy drop method is conducted, and doing work efficiency of reheater has different choices. A universal formula is raised to calculate flow of reheater when a unit of work substance is pushed out from extraction steam in reheating unit, and verified by examples.
