Chapter 10, Problem 64P
A Kaplan (propeller with variable-pitch blades) turbine with a rated capacity of 83 MW at a head of 24 m and 86 rpm was one of 14 units installed at the McNary project on the Columbia River. The characteristic runner diameter is 7 m. If a 6-m head is available in the laboratory, what should be the model scale, flow rate, and rpm?
