Question: question 4 a 1 20 scale model of a surface...

Question details

Question 4 A 1 20 scale model of a surface vessel is used to test the influence of a proposed design on the wave drag A drag of 27 5 N is measured at a model speed of 2 4 m/s 21 What speed does this correspond to on the prototype, and 22 What drag is predicted for the prototype? Neglect viscous effects and assume the same flud for model and prototype You can assume Co to be the same for both the model and the prototype (10) (10) [20]
