A model of a ship made to 1/20 scale, with wetted area 4 m², is towed in fresh water at 1.2 m/s. The measured resistance is 46.2 N. From tests on a thin plate of the same length as the model, the skin resistance is found to be 5.22 v1.95 N/m². Assuming skin resistance of the full-scale ship to be 4.95 v1.9 N/m². Find the total resistance of the ship in sea water at the speed corresponding to the model speed of 1.2 m/s. Density of sea water 1025 kg/m³. (327.5 kN)
