While preparing an experiment of a scale model submarine in a wind tunnel, for conditions of dynamic similarity, it is calculated that the wind speed is required to be 120 m/s. Which one of the following options will not help to reduce the air velocity of the wind tunnel?

Resistance R to the motion of a completely submerged body is given by R = ρV2 L2 φ , where ρ and ν are density and kinematic viscosity of the fluid while L is the length of the body and V is the velocity of flow. If resistance of a one-sixth scale airship model when tested in water at 10 m/s is 230 N, what will be the resistance in air of the airship at the corresponding speed? Kinematic viscosity of air is 13 times that of water and density of water is 810 times of air.
