at a head of 5.0 m when running at 300 rpm.
sec
What type of pump will be used? Suppose the required speed is 350 rpm.
What could then be done?
2. Under normal operating conditions a centrifugal pump with an impeller
diameter of 8.0 cm delivers 12 L/sec of water at a head of 262 m with
efficiency of 60 percent at 18,000 rpm. Compute the peripheral velocity,
the specific speed and Øe.
