1)The model of the torpedo (a military vehicle that goes very fast underwater) as placed in a tank is moved by being towed at a speed of 14,4 m/s. In the prototype, the torpedo is expected to move at a speed of 4.2 m/s in water at 15°C. The kinematic viscosity of water at the same temperature is v=3.4x10^(-3) m2/s. a) Determine the scale of the model used. b) If the same prototype and the torpedo model, prepared in the same size, is moved in a wind tunnel where u air=1.975×10^(-4) Ns/m2 and p air=22.5 kg/m3 air with physical properties under 10 atmospheres pressure and 26 C° constant temperature are used. What is the speed of the torpedo?
