Fluid mechanics ch.9: A supertanker has length, breath, and draught (fully loaded) dimensions of 325m, 48m, and19m, respectively. In open seas the tanker normally operates at a speed of 115 kt (1 kt=0.515m/s). For these conditions, and assuming that flat-plate boundary-layer conditions are approximate, estimate the skin-fraction drag of such a ship steaming in 10 degrees celcius water. What power is required to overcome the skin friction drag? What is the boundary-layer thickness at 300m from the bow?
