Sulzer Hydro Ltd. of Zurich at one time manufactured a six-jet vertical-shaft Pelton wheel turbine with a power rating of 174.4 MW, with a runner diameter of 4.1 m, and an operating speed of 300 rpm with an effective head of 587 m. Assuming the overall efficiency is 0.90 and the nozzle efficiency is 0.99, determine
a. the power specific speed;
b. the blade speedjet speed ratio;
c. the volume flow rate
Considering the values shown in Figure 9.2, comment on your result.
