A fighter aircraft is to operate at 200 m/s in air at standard conditions (p= 1.2 kg/m³). A model is constructed to 1/20 scale (length ratio) and tested in a wind tunnel at the same air temperature (same air viscosity) to determine the drag force. The drag force Fp is a function of the air density p and viscosity µ, the velocity V and the cross section length of the airplane D. a) Use dimensional analysis to prove that: F, and PV²D² pVD What are these two dimensionless numbers? b) If the model is tested at 50 m/s, what air density should be used in the wind tunnel? Comment the result and give a recommendation. c) If the model drag force is 250 N at 50 m/s, what will be the drag force of the prototype? Lift force 200 m/s Drag force

Here, there is a human powered submarine. The length of the submarine is 4.85 m and the hope is it can travel fully submerged through water at 0.440 m/s. The water it is being tested in is freshwater at a Temperature of 15 degrees celcius. The submarine model is built on a 1/5 scale and is built in a wind tunnel. A shield surrounds the drag balance strut so that the aerodynamic drag of the strut itself does not influence the measured drag. Here, the wind in the wind tunnel is at 25°C and at one standard atm pressure. What air speed is needed to run the wind tunnel in order to achieve similarity?
