a test tank will be used to measure the drag of a scale model ship 0.8 m long. This model bears full resemblance to a 40 m long prototype ship that was designed to sail at a speed of 10 m / s.

a) model speed

b) the ratio between model and prototype drag windows c) a ratio between the powers needed to overcome the drag of the model and the prototype take the number of froud into account in your analysis.
