A 1 /25 model of a ship with a wetted area of 800

is cowed in a water basin at a speed of 2.0 m/s. The model experiences a resistance of 20 N. Calculate (a) the speed of the prototype, (6) the drag on the ship due to wave, (c) the skin friction, assuming that the skin-drag coefficient for the model is 0.004 and for prototype 0.015, (d) the total drag on the ship, and (e) the power to propel the ship.
