Problems (cont.) Pb 15.4.1 A model centrifugal pump has a scale ratio of I:15. The model tested at 3600 rpm, delivered 0.10 m/s of water at a head of 40 m with an efficiency of 80 percent. Assuming the prototype has an efficiency of 88 percent, what will be its speed, capacity, and power requirement at a head of 50 m? Solution
