A propeller (diameter D = 15 m) rotates at N = 1 revolution per second (rps). To understand the flow around the propeller, a lab-scale model is made. Important parameters to study the flow are velocity of the propeller tip (V = ฯ€ND), diameter D and acceleration due to gravity (g). The lab-scale model is 1/100th of the size of the actual propeller. The rotation speed of the lab-scale model, to the nearest integer, should be

Correct : 10
