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.

2. A pump is required to draw 50 of water from reservoir A, with static suction lift of 4.5 m to reservoir B, with static discharge head of 15 m. The pipe in the suction line is 6 in nominal diameter and 8 m long. The pipe in the discharge side is 4 in nominal diameter and 15 m long. The fittings and valves installed in the suction line are: one foot valve, one standard elbow and one gate valve; and in the discharge line are: one check valve, one gate valve, two standard elbows. Assuming an absolute roughness of 0.24 mm for a cast iron pipe, and an absolute viscosity of water of 0.01002 poise, and neglecting the head loss in the foot valve and at the exit in the discharge reservoir, determine the pump brake power if the pump efficiency is 82%. Draw the piping system.
