You and your workmate are choosing pumps for your design. You've already decided which centrifugal pump you will use. The next thing you would think about this time would be the shape of it's impeller blades. The impeller in your design would have a revolution of 565 rpm, will have a volume flow rate of 11.7 gals per min and will (discharge) head of 2222 cm. Your coworker said that axial flow pump is your choice. Would you agree? Why or why not? Prove it.
