A flow rate of 0.14 m3 / s is required from a centrifugal pump with an outer radius of 23cm and rotating at 900 rpm. The width of the propeller is b = 8cm (at the outlet). Assuming 73% efficiency, what motor horsepower is required if the outlet angle is 165º? Suppose the pallets occupy 5% of the exit surface.
