A company manufactures geometrically similar airplane propellers up to 4.0 m in diameter. Wind tunnel tests are run on geometrically similar propellers up to 0.33 m in diameter. In the test of

a 0.33-m model of a 4.0-m propeller, the air velocity was 50 m/s.

The model rotational speed was 2000 rpm, the thrust 100 N, and

the propeller input torque 20 N ∙ m. Calculate the corresponding

prototype rotational speed, thrust, and input torque for an airplane

speed of 100 m/s. The Reynolds numbers and Mach numbers are

of minor importance.
