This loss is now to be recomputed for the rotor.
The off-design characteristics of a turbine are as important to define as the design-point characteristics. Figure 9-29 shows the effect of the speed-to-pressure ratio on the work output. It is obvious from these diagrams that turbine inlet temperature and pressure ratio are the two factors that affect the turbine output most significantly. To obtain these off-design perform-ance characteristics， it is necessary to study the effect of various dimension-less parameters， such as pressure and temperature coefficients， as a function of the flow coefficient. Other techniques used to study flow phenomena and distribution of the flow through the blade are also used for determining off-design conditions.
