The ratio of length of a submarine and its model is 30:1. The speed of submarine (prototype) is 10 m/s. The model is to be tested in a wind tunnel. Find the speed of air in wind tunnel. Also determine the ration of the drag (resistance) between the model and prototype. Take the value of kinematic viscosities of sea water and air as 0.012 stokes and 0.016 stokes respectively. The density of sea water and air is given as 1030 kg/m³ and 1.24 kg/m' respectively. CO3 K5 (08) The ratio of length of a submarine and its model is 30:1.
