1. A torpedo-shaped object 900 mm diameter is to move in air at 60 m ·s−1 and its drag is to be estimated from tests in water on a half-scale model. Determine the necessary speed of the model and the drag of the full-scale object if that of the model is 1140 N.
2. Show that, for flow governed only by gravity, inertia and pressure forces, the ratio of volume flow rates in two dynamically similar systems equals the 5/2 power of the length ratio.
