1. A Catamaran is a sailboat with two aerodynamically shaped hulls of equal size. The length of each hull is 14 m and the section submerged in sea water can be approximated by a triangular cross section tapered at the front as shown in the figure below for both hulls, with the wetted length of each submerged side being 0.3 m. Determine the drag due to shear stress on the two hulls if the top speed of the boat is 40 km/hr and the critical Reynolds number is 106. For sea water use p = 1027 kg/m3, and u = 0.0014 N - s/m². 640 F 0.3
