The S-shaped head-versus-flow curve in Fig. occursin some axial-flow pumps. Explain how a fairly flat systemloss curve might cause instabilities in the operation of thepump. How might we avoid instability?
The head-versus-flow-rate characteristics of a centrifugalpump are shown in Fig.. If this pump drives water at20°C through 120 m of 30-cm-diameter cast iron pipe,what will be the resulting flow rate, in m3/s?
The design of a new dam reveals that a water head of 10 meter and water flow rate of 100 cubic meter per second (m3/s) can be supplied for electricity generation. What kind of turbines would you recommend for the electric power generation?
