(Refer to Example Problem 11.8.) Water at 50^{ \circ} F flows at a velocity of 9 ft/sec over aprototype 30-ft-long streamlined hull with a width of 30 ft and a depth of 4 ft, as illustrated in Figure EP 11.9. A smaller model of the larger prototype is designed in order to study the flow characteristics of the flow over the streamlined body with wave action at the free surface. The model scale, λ is 0.20. (a) Determine the drag force on the prototype streamlined hull. (b) Determine the model fluid and the velocity of flow of the model fluid over the model streamlined hull in order to achieve dynamic similarity between the model and the prototype. (c) Determine the drag force on the model streamlined hull in order to achieve dynamic similarity between the model and the prototype.
