Turbine operation, general characteristics,tions are processes where a large amount of fluid energy is dissipated in valves or other throttling devices. In some processes dissolved gases separate from the fluid or liquid is flashed into steam during the expansion. Higher energy differences are then available for power recovery than in pure l

T. Frauenstein,U. Pape,O. Wagner= 1. Overload corresponds to q* > 1, while operation at q* < 1 is called “partload”. The pump characteristics describe the behavior of head, power consumption and efficiency as functions of the flow rate (the behavior of NPSH = f(Q) is discussed in Chap. 6). The shape of these performance curves ove
