A centrifugal pump has a 41.5-in-diameter impeller. It is used to deliver water at about 12,000 gal/min. Its pump performance curve when spun at 710 RPM is shown in the figure below. If the impeller is trimmed to a new diameter of 39.5in, estimate the new head (in feet) and flow (in gal/min or GPM) if the speed is not changed. a. 11244 gpm, 283 ft b. 11422 gpm, 283 ft c. 11422 gpm, 238 ft
