1 引言采用热力学法测定水轮机或水泵水轮机的效率时,只需测量水轮机或水泵水轮机进水断面和出水断面的水压和水温,就可以求出其效率。除热力学法外,其他各种效率测定
1 Introduction Thermodynamic method to determine the efficiency of a turbine or a pump turbine can be obtained simply by measuring the water pressure and water temperature at the inlet and outlet sections of the turbine or pump turbine. In addition to the thermodynamic method, various other efficiency measurements
