QUESTION 3 A boat is equipped with two retractable rudders of width 0.75m and length 1m. The speed of the boat is 120km/h. 3.1 What is the skin drag on the rudders if transition occurs at Recr = 5 x 105? The water is fresh water at 15ºC. 3.2 After a whole season of use, the drag on the rudders were measured to be 8400 N. Calculate the roughness of the rudders. HINT: Make an assumption and then check your assumption afterwards.
