Question: Consider a 1/4 scale model turbine and its equivalent full-scale prototype turbine, both operating at their best efficiency point, and at the same rotational speed.

Consider a 1/4 scale model turbine and its equivalent full-scale prototype turbine, both operating at their best efficiency point, and at the same rotational speed. Both are operating with water at 20oC. Which of the following statements is false? The net head across the model turbine will be approximately 1/8 times the net head across the prototype turbine. The prototype turbine will probably have a higher efficiency than the model turbine. The flow rate through the prototype turbine will be approximately 64 times the flow rate through the model turbine. The states of the two turbines are homologous
