Answer:
The ratio of the drag coefficients is approximately 0.0002
Step-by-step explanation:
The given Reynolds number of the model = The Reynolds number of the prototype
The drag coefficient of the model, = The drag coefficient of the prototype,
The medium of the test for the model, = The medium of the test for the prototype,
The drag force is given as follows;
We have;
Therefore;
= (1/17)^3 ≈ 0.0002
The ratio of the drag coefficients ≈ 0.0002.
