Question:

A certain pump is known to have a capacity of $3 \mathrm{~m}^{3} / \mathrm{s}$ when operating at a speed of $60 \mathrm{rad} / \mathrm{s}$ against a head of $20 \mathrm{~m}$. Based on the information in Fig. 12.18, would you recommend a radialflow, mixed-flow, or axial-flow pump? Draw a sketch of the pump impeller (front and side views).
