A 1/ 50 scale model is built for a ship 90 m long that is cruising in a river with a water of kinematic viscosity of 1 X
/s at a speed of 40 km/h. The model is tested in a towing basin containing a liquid of specific gravity of 0.94. Determine the kinematic viscosity of the liquid to be used in the model to satisfy both the gravity and viscous constraints. At what speed should the model be tested and what force in the prototype corresponds to a force of 64 kg-m/ in the model?
