For the 6 × 8 - 17 centrifugal pump performance curve shown in Fig. 13.32, determine the capacity that can be expected from a pump with a 15-in impeller operating against a system head of 200 ft. Then, compute the specific speed and specific diameter and locate the corresponding point on Fig. 13.53.
